Answer:
17
Step-by-step explanation:
the rise is the new minus the old.
9 - -8 = 9+8 = 17
Answer:
Then the desired equation is y = -2x - 6.
Step-by-step explanation:
As we move from point (-3, 0) to point (0, -6), x increases by 3 and y decreases by 6. Thus, the slope of the line segment connecting these two points is m = rise / run = -6/3 = -2.
Now use the slope-intercept equation of a straight line to determine the y-intercept of this line:
y = mx + b becomes 0 = -2(-3) + b, so that b = -6.
Then the desired equation is y = -2x - 6.
Check: Does (0, -6) satisfy y = -2x - 6? Is -6 = -2(0) - 6 true? YES
I'm gonna do this 2 ways because I'm not sure what you mean about the line. I'm going to indicate greater than or equal to with >=.
1st I'll solve for
r/15 >= -3
multiply by 15 on each side
r >= -45
Next I'll solve for
r/15 >= 3
multiply 15 on each side
r >= 45
So depending on if that is a 3 or -3 that is how you would do it....
So did I read the problem right?
Answer:
The answer to your question is below
Step-by-step explanation:
In blue is f(x) = x² + 3
in red, x =1
F(1) = 1 + 3
= 4
Point = (1,4 ) in yellow
