To find the slope you want to use the formula:
m = y2–y1/x2–x1
m = (3–1)/(-5–1)
m = 2/-6
To find the y-intercept:
Substitute the y part of the point and solve for b
Y = mx + b
1 = (2/-6) + b
1–(2/-6) = (2/-6) – (2/-6) + b
4/3 = b
Slope-intercept form is:
Substitute in slope and y-intercept
Y = mx + b
Y = 2/-6x + 4/3
