Add 10 To Both Sides

Subtract 7x From Both Sides

Simplify

Divide Both Sides By -2

Simplify

The answer I believe is 30
<span>5y = 10x - 15
y = -5x - 3
so slope = -5
x - intercept when y = 0
</span> -5x - 3 = 0
-5x = 3
x = -3/5
(-3/5, 0)
y - intercept when x = 0 then y = -3 (0,-3)
answer
slope = -5
x-intercept (-3/5, 0)
y-intercept (0, -3)
