Well you would have to use the formula x= -b/2a to find the value of x and then substitute that value of x in the equation to find y<span />

The vertex formula is derived from the completing-the-square process, just as is the Quadratic Formula. In each case, memorization is probably simpler than completing the square.) For a given quadratic y = ax2 + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k.

Find the y-intercept and the slope of 12x-4y=7

den301095 [7]

Answer:

The slope is 3 and the y intercept is -7/4

Step-by-step explanation:

We need to get the equation in the form

y = mx+b where m is the slope and b is the y intercept

12x - 4y =7

Subtract 12x from each side

12x-12x -4y = -12x +7

-4y = -12x+7

Divide each side by -4

-4y/-4 = -12x/-4 +7/-4

y = 3x + -7/4

The slope is 3 and the y intercept is -7/4
