Answer:
y = 12x
Step-by-step explanation:
This is your current equation: y=12x + b. Plug in the point to your equation, it should look like this: 12 = 12(1) + b. 12 times 1 equals 12. This is what you should have now: 12= 12 + b. Subtract 12 from both sides to get 0 = b. Because the y-intercept is 0, you can just write your final equation as y= 12x. Hope this helped!
