Question

Which of the graphs below represents the equation 8x-y=4

Answer 1

Graph Z

Slope: 8

Y-Intercept: -4

Answer 2

Graph X

Explanation:

`8x-y=-4`

To graph the equation we write it in the form of y=mx+b

Subtract 8x from both sides

`-y=-8x-4`

Divide both sides by -1

`y=8x+4`

In y=mx+b, m is the slope and b is the y intercept

`y=8x+4` , slope =8 and b=4

Now make a table , plug in some random number for x and find out y

x y=8x+4

-1 -4

0 4

Two point on graph are (-1,-4) and (0,4)

Graph x is the correct graph
