Answer:
Step-by-step explanation:
The answer is c.
Proportional means a relationship of y = a constant multiplied by x
In this case, the constant is 7.
i.e. y = 7x
So if
x is 3, y is 21
x is 5, y is 35
x is 7, y is 49
and so on...
And there you have it.
Answer:
5
Step-by-step explanation:
15 × 
= 5
Answer: y = -2x +5 , so C (you probably just forgot to put the x)
Explanation: y = mx+b m represents the slope, b represents the y intercept
Answer:
Graph C with the green dots.
Step-by-step explanation:
y = 0.5x + 5 is a linear equation, so we can rule out A because it is not straight.
5 represents the y-intercept, so we rule out B because that graph doesn't intercept the y-axis at (0,5).
Graph C represents a straight line that passes through (0, 5) & has a 0.5 slope, so that is our answer.
Hope this helps. :0)
A linear equation can be represented by:
y = mx + b
Where m = slope, and b = y intercept.
The slope is a rate of change, so our slope is $150.
The y intercept is the point where the equation crosses the y axis, or the "initial amount" in this case $500.
So our equation will be:
y = 150x + 500.
