hello
so the image is a bit blurry for me but i'll do my best. if any of my numbers are wrong just change it and re-calculate.
first we want to find the slope which we can do using
so our (
) would be (0,-7) (
) would be (5,-10)
when we input it into the slope equation we should get m=(-10+7)/(5-0)=-3/5
slope intercept form is: y=mx+b
our b, or y-intercept, is -7 as that is the point the line crosses the y-axis
so if we input everything we should get: y=(-3/5)x-7
hope this helps
have a nice day :)
