Answer:

Hope I'm not too late for this...

(look below)

Step-by-step explanation:

For the first part:

1. b = -1, m = 2

The y-intercept (b) is the value of y when x = 0. In this case, we can see that when x = 0, y = -1 so the y-intercept is -1.

The slope was found using the equation slope (m) = (y2-y1) / (x2-x1) and two points. (Note, you can choose any two points, I just chose the first two.)

(5,9) (-2,-5)

slope = (y2-y1) / (x2-x1)

slope = (-5-9) / (-2-5)

slope = -14/-7

slope = 2

I used the same steps as shown above:

2. b = 2, m = -3

For the second part:

1. y = 2x - 1

2.y = -3x + 2

I basically plugged in the values for m and b into the equation, y = mx + b.

Graphs:

The way to graph a line is to plot at least two points and draw a line through them. You can graph it using either the equation or the table. I used the table since it is much easier to find the points that I need.

Below I have included references to what the graph should look like if you need to check your work.

The one in blue is for the equation y = 2x - 1. This should help you get a visual of what the correct graph looks like.

The one in green is for the equation y = -3x + 2.

I hope this helped!
