Question

What are the intersections of the graphs of these equations with the x-axis? y=0.4x-12

Answer 1

Answer:

The graph of any curve intersects the x axis, at y = 0.

So,

y = 0.4x - 12 intersects x axis at y = 0

That is,

0.4x - 12 = 0

0.4x = 12

x = 12/0.4

x = 30

Therefore the graph intersects the x axis at (30,0)

Answer 2

Answer:

(30,0)

●Step-by-step explanation:

You need to find the x point so set y to 0.

0.4x=qw

x=30

the point is (30,0)
