Answer:

Step-by-step explanation:

The slope is given as m = 2

The general equation is y = mx + b

So far what we have is y = 2x + b

The y intercept is the value of y when x = 0

-4 = 2(0) + b

b = - 4

Therefore the equation is y = 2x - 4

This is not a right triangle because the hypotenuse is less than the two sides and aren't equal when following the Pythagorean thm

Step-by-step explanation:

To confirm if a triangle is a right triangle, we must use the Pythagorean thm

a^2 + b^2 = c^2

23^2 + 11.4^2 = 21.2^2

529 + 129.96 = 449.44

658.96 ≠ 449.44
