Answer:

y=2x+3

Answer:

15 units

Step-by-step explanation:

The distance between two points can be found using the following formula:

$d\sf=\sqrt{(x_2-x_1)+(y_2-y_1)}$

Given points:

(-7, 5) and (2, -7)

where:

x₁ = -7
x₂ = 2
y₁ = 5
y₂ = -7

Substitute these points into the formula and simplify:

$\sf d=\sqrt{(2-(-7))^2+((-7)-5)^2} \ \textsf{[simplify the radicand]}\\\\ d=\sqrt{(2+7)^2+(-12)^2} \ \textsf{[simplify]}\\\\d=\sqrt{(9)^2+(-12)^2} \ \textsf{[evaluate the power]}\\\\d=\sqrt{81+144} \ \textsf{[add]}\\\\d=\sqrt{225}\ \textsf{[simplify]}\\\\d=15$
