Question

Find the x- and y-intercepts of the graph of 10x + 9y = 40. State each
answer as an integer or an improper fraction in simplest form.

Answer 1

Answer:

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

Step-by-step 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.
