X = -5
so f(-5) = 6(-5)+7
f(-5) = -30 +7
f(-5)= -23

You would substitute or plug in -5 wherever there is an x in the equation.

f(-5) = 6(-5) + 7
f(-5)= -30 + 7
f(-5) = -23

Find the distance between the two points.

Ksenya-84 [330]

Hey there!

Distance formula:

d = $\sqrt{(x_{2}-x_{1})+(y_{2}-y_{1}) }$

Plug in variables:

d = $\sqrt{(0-(-6))+(0-(-7))}$

Simplify.

d = $\sqrt{6+7}$

d = $\sqrt{13}$

The distance between the two points is $\sqrt{13}$ units.

Hope this helps!
