Answer:

2, -5

Explanation:

Ideally, we shift this to slope-intercept form to easily read it. But it can be as simple as dividing out the GCF

8x - 4y = 20

The greatest factor that 20, 8, and 4 share is 4. Thus, we divide by 4 on both sides.

8x/4 - 4y/4 = 20/4
2x - y = 5

We are left with slope-intercept form, but not in the proper order.

It's readable now, but for the sake of consistency, we will rearrange it.

2x - y + y = 5 + y
2x - 5 = 5 + y - 5
y = 2x - 5

Since slope-intercept is y = mx + b where m is the slope and b is the y-intercept, the slope is 2 and the y-intercept is -5.

Answer:

Slope = 2

y-intercept = -5

Explanation:

Slope y-intercept form: y = mx +b

m is the slope and b is the y-intercept.

8x - 4y = 20

-4y = -8x + 20

Isolate 'y' by dividing both sides by (-4),


\sf (-4y)/(-4)=(-8x)/(-4)+(20)/(-4)

y = 2x - 5

Slope = 2

y-intercept = -5
