C. 3w + 8 - w = 4w - 2(w - 4)

(3w - w) + 8 = 4w - 2w -2(-4)

2w + 8 = 2w + 8

Through (-1,5) , perp to y =1/9x+2 write the slope intercept form for the equation
ycow [4]

Answer:

y=-9x-4

Step-by-step explanation:

Perpendicular lines meet the following condition:

m2*m1= -1 (a)

where m is the slope of a line

m1 is given through equation of line 1, y =1/9 x+2

m2 must be -9 -> from eq. (a)

The Line has the following equation: y=mx+b, where m=-9 and the b is the interception with y axis.

Evaluating the above equation in (-1,5) we have the following equation

5= -9*(-1)+b, we have b=-4

The line has the following equation

y=-9x-4
