Aparking space shaped like a parallelogram has a base of 17 feet and a height is 9 feet. a car parked in the space is 16 feet long and 6 feet wide. how much of the parking space is not covered by the car?

First, we have to get the area of the parallelogram. A = b x h. 
A = 17 feet x 9 feet
A = 153 square feet.

The area of the car (assume that the car is rectangle) is equal to: A = l x w.
A = 16 x 6
A = 96 square feet.

The space that is not covered by the car is 153 - 96 = 37 square feet.

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
