2 Question *
(1 Point)
2.7. Jon throws a ball into the air off a platform. The height of the ball is given by
y = -2x2 + 11x + 21, where y is the height, in feet, above the ground when the ball has traveled a
horizontal distance of x feet. What is the factored form of the expression that could be used
to find out how far the ball has traveled horizontally when it hits the ground?
A. (x + 7)(-2x + 3)
B. (x - 7)(-2x - 3)
C. (2x + 7)(x + 3)
D. (2x - 7)(x-3)

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

3; 9 is 8 to -4

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
