Answer:
-5/-2 or 2.5
Step-by-step explanation:
Because you gave two points that I'm guessing are from the graph I think that's the answer. Because when you use the slope formula y2-y1 over x2 - x1 you get -5/-2 or you either get 2.5 meaning that is the slope specifically saying the rate of change. You get 2.5 when you divide -5/-2 incase you need a decimal or want to simplfy it.
Answer:
y=2
Step-by-step explanation:
Answer:
The value of a is "3", to complete the coordinate point (3,7) on the line.
Step-by-step explanation:
We are given the slope of the line, and also one point through which the line passes. Therefore, we can find the actual equation of the line by using the slope-point form of the line:

Now, we need to find which value of "x" renders a y-value of "7", to complete the coordinate pair (a, 7) as requested. Therefore, we ask for the y-value in the previous equation to be "7", and solve for its associated x-value:

Therefore, x = 3
30 inches of ribbon because in one foot there are 12 inches so in 2 feet there are 24 inches. And 30 is greater than 24 so therefore 30 inches of ribbon is longer than 2 feet of ribbon
