This question, i also need with, again--if anyone can answer this; you will receive 50 points and brainliest answer.

Slope intercept form of a line:

y=mx+b

Where m is the slope and b is your y intercept

4x-8y=8

TO begin to isolate y, perform the opposite operation by subtracting 4x on both sides of the equation

4x will cross out on the left

4x - 4x =0

You're left with:

-8y=-4x+8

Perform the opposite operation by dividing both sides of the equation by -8

-8 will create 1 on the left:

-8÷-8=1

on the right:

4÷-8= -1/2

8÷-8=-1

Now the equation looks like (this is the first answer):

y=-1

Now, for part b, you can look at the above equation and to know that the slope is - and the y intercept is -1

For part c, remember that perpendicular lines have opposite reciprocal slopes. So, use the slope from y=-1, which is -1/2, and use its opposite reciprocal: 2

To write an equation using the points and slope of 2, plug the numbers into point slope formula:



Where:

(1,2) ⇒

y-2=2(x-1)

Distribute the 2 throughout the set of parenthesis

y-2=2x-2

Add 2 on both sides of the equation

y=2x+0

Answer for c:

y=2x
