Question

what is an equation in point-slope form of the line that passes through the given point and with the given slope m (-5,1);m=4

Answer 1

Equation for line: y=mx+b where m is the slope and b is the y-intercept

We have the slope. We just need to find the y-intercept. Plug in the point and the slope and solve for b.

y=mx+b

1=4(-5)+b

b=21

Answer: y=4x+21
