Question

the equations y = x + 20 and y = 8x
intersect in the xy-plane?
A.
0
B.
1
C. 2
D. 8

Answer 1

The graphs of the equations y = x + 20 and y = 8x intersect at a single point in the xy-plane.

Step-by-step explanation:

To find the points where the graphs of the equations y = x + 20 and y = 8x intersect in the xy-plane, we need to set the two equations equal to each other and solve for x.

x + 20 = 8x

Subtracting x from both sides, we get:

20 = 7x

Then divide both sides by 7:

20/7 = x

So, the two graphs intersect at a single point.
