Answer:
The quantity telling us how much y changes for a one-unit increase in x is called the slope.
Step-by-step explanation:
We are given the following in the question:
The linear equation is given as:
[tex]y = a + bx[/tex]
Slope is the quantity telling us how much y changes for a one-unit increase in x.
It is represented by "b" in the given linear equation.
It can be shown as:
[tex]y = a + bx\\y_1 = a + b(x + 1)\\y_1-y = a + b(x + 1)-( a + bx)\\y_1-y = b(x+1-x)\\b = y_1-y[/tex]
