Question

Choose the equation below that represents the line passing through the point (−3, −1) with a slope of 4.

a. y = 4x − 11
b. y = 4x + 11
c. y = 4x + 7
d. y = 4x − 7

mathmale · Answer

All four of the answer choices are in the "slope-intercept form" of a straight line.
Start with this form:  y=mx+b.  Substitute the slope (4) and the coordinates of the point (-3,-1) into this equation.  Solve / evaluate the result for b.

Then re-write this same equation, in the form y=mx+b.
