Question

Which line has a slope of zero and goes through (5, -8)

Answer 1

Answer:

y=-8

Step-by-step explanation:

From the information given, we know that the slope of the line is 0. Let's make an equation in y=mx+b form with what we know.

y=0x+b

We also have a point on the line, (5, -8). We can plug these two numbers for x and y to find b and complete the equation. -8 goes in as y and 5 goes in as x.

-8=0(5)+b

Now just solve for b.

-8=0+b

b=-8

We now know that b is -8 and can complete the equation.

y=0x-8

y=-8
