Answer:
D. X=-3, y=4
Step-by-step explanation:
-2x+3y=18 equation 1
x=-y+1 equation 2
-2(-y+1)+3y=18 replace x value of equation 2 into equation 1
2y-2+3y=18
5y=20
y=4
solve for x by replacing y value into either equation.
x=-y+1
x=-4+1
x=-3
The slope is -1/4.
Assuming you know the rise over run method, at point (-8, -3) you go down once (-1) and to the right 4 (+4) to get to the next point on the line. When you convert it to a fraction, the slope is -1/4.
Substitute in x to get:
4^2 = 16
16 - 5 = 9
The average rate of change over an interval can be found with the following formula:

The parabola goes through (2, -3) and (3, -1). We want to find the average rate of change over the interval [2,3]. Plug these values into the formula:

The average rate of change will be
2.
