The standard form of the equation of a parabola is y=-2x-8x-13. what is the vertex form of the equation?

Presuming you mean y = -2x^2 - 8x - 13

Firstly, put the x terms in parentheses and factor out -2:

Next, we want to make what's inside those parentheses a perfect square. To do this, divide the x coefficient by 2 and square that result. In this case, that result is 4. Add 4 to the inside of the parentheses, and add 8 to the outside of the parentheses to balance it out. (Since when foiled, 4 x -2 = -8)

Next, factor what's inside the parentheses, and your final answer will be

90% rotation

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
