Answer:
y = -3/4x + 7
Explanation:
ok first u need to find the slope so use the slope equation for this (x2 - x1 over y2 - y1) so
1 - 4 = -3
8 - 4 4
so the m is -3/4
now you need to find the y intercept so pick one of the points (let's do (8, 1)) and plug that into the slope intercept form (y = mx+b)
so 1 = -3/4(8) + b
1 = -6 + b
+ 6 + 6
b = 7
so the equation is y = -3/4x + 7. hope this helps
