Given the following information, write the equation of the line in slope-intercept form. Slope = -8 and y-intercept = 4
Montano1993 [528]

Answer:

y = -8x + 4

Step-by-step explanation:

Using the y = mx +b for the slope intercept form, the m stands for the slope and the b stands for the y-intercept.

In this case, the slope is -8 and the y-int is 4 so we naturally plug those in

Hello,

To solve we need to factor y^2-2y-35:

(y-7)(y+5)=0

Now solve for :
