Identify the x-intercept and y-intercept of the equation below. 9x-7y=21

Hi there! To find your x intercept, you need to replace your y variable with 0 (because your x intercept is the coordinate at which y is 0). Then, solve for x. The x-intercept in your problem is (21/9, 0). Then, to find your y intercept, you need to replace your x variable with 0. Then, solve for y and you will get (0,-3). I hope this helps you!!! :))

X-intercept=-21/9
y-intercept= 21/7
These arent simplified but if the x and y intercept were simplified it would be:
X-intercept=-7/3 or -2.33333
y-intercept= 3

'a number' means x

A. a number times 7 means x times 7 or 7x, yep
B. a number subtracted from 7 means 7-x, yep
C. sum of a number and 7 means add them so 7+x, yep
D. a number divided by 7 means x/7, this is the wrong one

D is answer
