Using the slope formula, if y = -58, slope is 7, and the y-intercept is -15, solve for x. slope formula: y = mx + b

The value of x would be roughly -6.14

Step-by-step explanation:

To find x, all we need to do is put each of these values in for the variables that they represent. y obviously goes in for y. y-intercept is the b value, and slope is the m value.

y = mx + b

-58 = 7x - 15

-43 = 7x

-6.14 = x

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
