Question

Does anyone understand how to do this? If you do can you explain how I solve it and receive the answer?

Answer 1

slope-intercept form equation: y = x + 5

Explanation:

you take the 2 y's, 18 and -13, then you subtract them: 18 - (-13) = 31

then you take the 2 x's, 13 and -18, subtract them too: 13 - (-18) = 31

divide those 2 sums: 31/31 = 1

so the slope is 1

then when you graph it you get an y-intercept of 5

so the equation is y = x + 5

hope this helps :)
