Using the slope formula, if y = -46, slope is 6, and the y-intercept is -13, solve for x. Slope formula: y = mx + b (Note: Only

hram777 [196]

Answer:

x = - $\frac{11}{2}$

Step-by-step explanation:

rearrange the formula, giving x in terms of b, y and m

given y = mx + b ( subtract b from both sides )

mx = y - b ( divide both sides by m )

x = $\frac{y-b}{m}$

evaluate using y = - 46, m = 6 and b = - 13

x = $\frac{-46-(-13)}{6}$ = $\frac{-33}{6}$ = - $\frac{11}{2}$
