Write an equation in point-slope form -2,-5 4,-1

Step-by-step explanation:

first find the slope

m = Δy/Δx = (-1 - (- 5)) / (4 - (-2)) = 4/6 = 2/3

Then plug either point into the equation

y - y₁ = m(x - x₁)

y + 1 = 2/3(x - 4)

which is equivalent to

y + 5 = 2/3(x + 2)

the line of

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
