Question

Please help explanation if possible

Answer 1

x-intercept (3,0)

y-intercept (0,7)

Explanation:

Plug in zero for x and y separately and solve for the variable.

x-intercept:

7x + 3(0) = 21

7x = 21

divide both sides by 7 and you get x = 3 so your x-intercept is (3,0)

y-intercept follows the same process:

7(0) + 3y = 21

3y = 21

y = 7 so your y-intercept is (0,7)
