Pool has 4 sides
So
22.3 + 22.3 = 44.6
75+75 = 150
150 + 44.6 = 194.6ft

Find the slope, x-intercept, and y-intercept of the equation y = 10x - 20.
levacccp [35]

Answer:

slope=10, y-int=-20. x-int=2

Step-by-step explanation:

The equation y=10x-20 is in slope-intercept form, or y=mx+b with m being the slope and b being the y-int. In this scenarion, the m(the slope) is 10 and the b(the y-int) is -20. For the x-int, you have to find out what x is when y=0 and vice versa for the y-int. In this case, 0=10x-20 so x=2. Therefor the x-int is 2.
