Answer: y= x-2
Step-by-step explanation:
Perpendicularity entails the slope of line a is -1 divided by the slope of line b
m1= (-1/m2)
From y=Mx +c
We compare with x-4y=7
y=(1/4)x-7/4
Meaning m2= 1/4
m1= -1/(1/4)= -1*4= -4
((y-y1)/(x-x1))= ((y2-y1)/(x2-x1))=m1
x1= 2, y1= -4
((y-(-4))/(x-2))= -4
((y+4)/(x-2))= -4
Cross multiply
y+4= -4(x-2)
y= x-2
Answer: w = 5
Step-by-step explanation:
Step 1: Take cube root.
w=(125) ^(1/3)
W = 5
The equation of the line through (-4, -5) parallel to 3x-4y=-8 can be written as
3(x-(-4)) - 4(y-(-5)) = 0
3x -4y - 8 = 0
3x - 4y = 8
