Question

On the graph of the equation 5x – 2y = 20, what is the value of the y-intercept?

Answer 1

When y-intercepts, x =0

5(0) - 2y = 20

Answer 2

5x+2y=20 is the same as

y=10-2.5x

Put values in for x and plot eg.

x=0, y = 10
x=1, y = 7.5
x=2, y = 5

Answer 3

The options are 4, -4, 10 or -10... And i'm not getting either of those..

Answer 4

Just use Saifoo's explanation and solve for "y" because at the y-intercept, x equals zero because that is where the line intersects the y axis.

Answer 5

I did, but it still didn't work...

Answer 6

5(0) - 2y = 20
0-2y = 20
-2y=20
solve for y

Answer 7

Okay, I got it now... thank you :)
