Answer:
D. -2 ≤ y ≤ 3
Step-by-step explanation:
This is because range is based on y-values and so the lowest y-value here is -2 and the greatest one is 3, inclusive.
Answer:
y-7=3(x-9)
Step-by-step explanation:
It appears they want your answer in point-slope form, which is identified by the equation y-y1=m(x-x1)
Step 1: Find the slope (m)
m=(y2-y1)/(x2-x1)
m=(-8-7)/(4-9)
m=(-15)/(-5)
m=3
The slope is m=3
Step 2: Plug in m, y1, and x1
y-y1=m(x-x1)
y-7=3(x-9)
Therefore our final equation is y-7=3(x-9)
Answer:
5 units
Step-by-step explanation:
The graph helps you measure it
You find the variable x or y in one of the lines of the problem and then substitute the value of the variable you first found into the other line of the problem to find the other variable. Then, you plug all of the values you found into either line/equation of the problem to ensure that one side of the equation you pick is equal to what is on the other side of the "=" symbol.
