If f(n)=5^n then what is f(4)

13) m = -4; b = 5; equation: y = -4x + 5

14) m = 1; b = 0; equation: y = x

15) m = -4; b = 3; equation: y = -4x + 3

16) m = 0; b = -4; equation: y = -4

17) m = 2; b = 4; equation: y = 2x + 4

18) m = -1; b = 3; equation: y = -x + 3

Step-by-step explanation:

To find the slopes of the lines, you need to do (rise/run) or (change in y/change in x). That means you need to find two points and apply that to them.

For example:

(a, b) and (c, d)

--> (d - b) / (c - a) = m

So that would be the slope

In order to find the y-intercept on the graph, just see where the line intersects the y-axis.

In the slope-intercept equation, you are putting it all together in the following equation:

y = mx + b

In this step, you just need to plug in the slope and y-intercept that you found earlier.
