Question

Help on Number 8? I know Y=5 and the slope is undefined and x=2 but I don’t know what to do now.

Answer 1

To find the slope, use the equation of a line: $y = mx + b$

Plug in the values for x and y:

$5 = 2x + b$

We know that 2 can fit into 5 twice, which means 2*2 is 4.

We now have $5 = 4 + b$.

If 5 is b more than 4, then this means that 4 is b less than 5. Subtract 4 from both sides, and you will have b = 1.

This means your equation is y = 2x + 1.
