We know, point slope form; (y-y1) = m(x-x1)
Here, (x1, y1) = (-1,6) & m = -2
So, it would be: y-6 = -2(x+1)
Hello!

Slope-intercept form is y = mx + b where:
m = slope
b = y-intercept
Plug in the given values:
y = 2x - 4
<span>1.7a+0.3a=4/5
2a = 4/5
a = 4/5 * 1/2
a = 4/10
a = 2/5
answer
</span> a = 2/5

Perpendicular because when graphed, it creates a cross, or an intersection at a 90 degree angle
