find the equation of a line with a slope of 2 and passing ... - Wyzant
May 26, 2017 · Alternatively, you could have used the slope-intercept form of the equation of a line, which is y = mx + b. We can use x = 1 and y = 2 since (1, 2) is a point on the line. The slope is represented by m, and it is 2. The letter b represents the y-intercept. 2 = 2 (1) + b. 2 = 2 + b. b = 0. The y-intercept is 0.
Slope, Gradient, and Slope Intercept - Wyzant Lessons
Examples of Slope / Gradient (1) Find the slope of the line between the points (1,2) and (3,6). (2) Find the slope of the line 3y = 2x + 1. This equation is not in slope intercept form, so we divide by three to find our m value. (3) Find the slope of the line 30 – 2y = -0.5x. Isolate y to put the equation in slope intercept form.
how would you write equation with a slope 2/3 and a y-interept of …
Dec 2, 2020 · With this information you can use the lineal equation in slope of a line form : m= (Y 2 - Y 1) / (X 2 - X 1) Substitute the values of your point (0, -3) and the value of the slope 2/3, and rewrite the equation: Y - (-3) / (X - 0) = 2/3. (Y + 3) / X = 2/3. Multiplying both sides of the equation by X. Y + 3 = (2/3)X, subtracting -3 in both sides ...
Slope of 2 and passes through (4,1) | Wyzant Ask An Expert
Slope intercept form looks like this: y=mx +b (or y= #x + #) m is the slope and b is the y intercept (the number that x equals when y equals zero) If the slope is 2, the equation is going to be y=2x + b, so we still need to find b. If we know that the point (4,1) is on the line, where x=4 and y=1, we can plug those numbers into the equation to ...
(2,-2) slope=2 how to put it in slope intercept form - Wyzant
Sep 30, 2012 · The equation of a line is given by: y = mx + b. where m = slope = 2 and therefore y = 2x + b. Since x = 2 and y = -2 (this is given by the point at (2,-2)), you can solve for b: -2 = 2 (2) + b. -2 = 4 + b. -6 = b. Thus the equation of the line that passes through the point (2, -2) and has slope = 2 is. y = 2x - 6.
Graph the line with the slope 3/2 and y-Intercept (0,-3)
High School and College Math & Science Tutor. Start with placing a point at the y-intercept (0,3). Slope is equal to "rise over run", which is the change in y over the change in x. So the change in y is +3 and the change in x is +2. So from (0,3) go up 3 and to the right 2 and place another point. This should be at (2,6).
passes through(1,9),slope=2 | Wyzant Ask An Expert
Nov 6, 2017 · Experienced Mathematics Tutor w/ Master's Degree in Math. See tutors like this. I imagine you want the equation of a line that passes through the point (1,9) and has a slope of 2. That means you should use the Point-Slope form of the equation of a line. y - y1 = m (x - x1) y - 9 = 2 (x - 1) y - 9 = 2x - 2. y = 2x + 7.
point (0,3) slope -2 | Wyzant Ask An Expert
Nov 2, 2017 · (2,-2) slope=2 how to put it in slope intercept form Answers · 3 Write the slope-intercept equation for the line that passes through (-14, -3) and is perpendicular to -7x – 4y = -4
Write the equation of the line that passes through point (6, 2
Jul 23, 2020 · In this equation, m is again the slope and x 1,y 1 is where you plug in points from the line. To solve this problem, plug in the given point to both forms of the equation to solve for the unknowns: 2 = (2/3)*(6)+b. 2 = 4+b. b= -2. so slope intercept form is y = (2/3)x -2. To find the point slope form, simply plug in m and the point given. y-2 ...
Through: (-2,1), slope = -1/2 | Wyzant Ask An Expert
Apr 2, 2020 · When we know the slope of a line and 1 point that the line passes through, we can use point-slope form to determine the equation of the line. Point-slope form: y-y_=m(x-x_) where (x_,y_) are the coordinates of the point the line passes through, and m is the slope of the line. Inserting our values we get y-1=-1/2(x-(-2))
