Answer 1

Answer:

The equation of the line is y=-1/2x-3.5

Step-by-step explanation:

Given the two points on the line, (1, -4) and (3, -5), find the slope of the line with the equation $m=\frac{y2-x2}{y1-x1}$.

$m=\frac{-5-(-4)}{3-1} =\frac{-5+4}{3-1} =\frac{-1}{2}$

After you find the slope of the line, substitute x and y with either point given to you. For me, I'll use point (1, -4) to solve for the y-intercept.

$-4=\frac{-1}{2} (1)+b$

$\frac{1}{2} -4=\frac{-1}{2} +\frac{1}{2} +b$    add both sides by 1/2 so that b is alone

$\frac{-7}{2} =b$              

You can rewrite -7/2 as -3.5.
