Write an equation in slope intercept form?

Question

Write an equation in slope intercept form for a line that passes through the point (-9,-1) and has a slope of -2

Answer 1

Slope Intercept form: y=mx + c

You can plug in the given values from the question to find "c":

x=-9

y=-1

m=-2

(-1) = (-2)(-9) + c

-1 = 18 + c

-1 - 18 = 18 + c -18

-19 = c

Final equation is y = -2x - 19
