Answer:

  • y-intercept = 40/9
  • x-intercept = 4

Explanation:

Let's re-arrange the equation.

  • => 10x + 9y = 40
  • => 9y = -10x + 40
  • => 9y/9 = -10x/9 + 40/9
  • => y = -10x/9 + 40/9

We can clearly see that the y-intercept is 40/9.

Please consider looking at the picture I uploaded. I can understand that it is blacked out but try your best to read the white-colored numbers.

When we look at the image, we can tell that the x-intercept is 4 because the line that is crossing on the x-axis is 4. Hence, the x-intercept is 4.

Hoped this helped.
