The slope of the graphed line is . Which formulas represent the line that is graphed? Check all that apply. y – 1 = (x – 2)
y – 2 = (x – 1)
y – 4 = (x – 4)
f(x) = x +
f(x) = x +

answer:

a=9

step-by-step explanation: lmk if you need a explanation

i believe it's a.

i'm not sure on this one, most likely correct.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
