Answer:
equation: y=35x+1200
a) the rate of change is 35.
b) 1200.
c) The Independent Variable is amount of students per year.
d) The Dependent Variable is the year
I'm not sure about the dependent varaliable, so don't take my word.
Subtract 5 from both sides
a/-8 = 4/7 - 5
simplify 4/7 - 5 to 31/-7
a/-8 = 31/-7
multiply both sides by 8
-a = 31/-7 x 8
simplify 31/7 x 8 to 248/7
-a = 248/7
multiply both sides by -1.
The answer is a = 248/7

It should be 49 feet long I’m not sure!
Answer:

Step-by-step explanation:
The slope-intercept equation takes the form

Where m is the gradient, and c is the y-intercept.
If we assume we are plotting a graph where the X axis is time, and the y axis is distance, and we know our time value starts at 40, then we can say that our y intercept value is 40.
Next, let's figure out how far she has travelled. 130-40 = 90, and she has travelled this distance in 30 seconds, so dividing 90 by 30, we know that she is travelling 3 feet a second. This leaves us with a gradient of 3.
Putting these two values together, we can find the final form of the equation to be:
