Answer:
x-intercept (3,0)
y-intercept (0,7)
Step-by-step 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)
