Enter the equation of the line in slope-intercept form. Slope is -1/2, and (-9,4) is on the line. The equation of the line is y=

Step-by-step explanation:

Hi there!

Slope-intercept form: where m is the slope and b is the y-intercept (the value of y when x is 0)

1) Plug in the slope (m)

We're given that the slope is . In , replace m with :

2) Determine the y-intercept (b)

We're given the point (-9,4). Plug this point into the equation as and solve for b:

Subtract from both sides to isolate b:

Therefore, the y-intercept is . Plug this back into as b:

I hope this helps!
