Question

a line passes through (1,5) and (-2,-1) find the slope-intercept form of the equation of the line. then fill in the value of the slope, m, and the value of the y-intercept, b , below

Answer 1

Answer:y=2x+3

Step-by-step explanation:

y=mx+b

m=$\frac{-1-5}{-2-1}$

=2

substitute 2 into the equation

y=2x+b

substitute any of the 2 points into the equation to find the value of b

-1=2(-2)+b

-1=-4+b

b=4-1

b=3
