Write an equation in slope-intercept form for the line with slope 3/2 and y-intercept -7. Then graph the line.

Question

I need help on figuring out how to write and graph an equation, please help me. 

Answer 1

slope intercept form is y=mx + b

 

Slope is m

y-intercept is b

 

y=(3/2)b - 7 

 

To plot, pick several values for x  and solve for matching y points and plot. We already know that y=-7 when x=0, so (0,-7) is a good place to start.
