find the y-intercept of the line by substituting 0 in for x and solving for y. y-12=4x

To find the y-intercept of the line given by the equation y - 12 = 4x, we substitute 0 in for x and solve for y.

Step 1: Substitute 0 in for x in the equation y - 12 = 4x. This gives us y - 12 = 4(0).

Step 2: Simplify the right side of the equation. 4 times 0 is 0, so the equation becomes y - 12 = 0.

Step 3: Solve for y by adding 12 to both sides of the equation. This gives us y = 12.

So, the y-intercept of the line is 12.
