Question

Which of these are the intercepts of the graph of y = 3x – 12?

Answer 1

Hello there! :) To find one intercept, you'll need to set the other one to 0. For instance: x intercept: y=0 y intercept: x=0 X Intercept: 0= 3x-12 Add 12 to both sides to isolate x. 0+12= 3x-12+12 12= 3x Divide both sides by 3. 12/3=3x/3 4= x intercept Y Intercept: You could plug in x as 0 and solve, but a quick way to find it in a slope-intercept equation is to look at the number at the end (without the x.) In this problem it would be -12. Hope this helps! :) Let me know if you need any additional helps.

Answer 2

Y intercept is (0,-12), the x-intercept is (4,0)
