Please help me I’m stuck on these questions :(

Step-by-step explanation:

4) Money per hour = Total Money / Total Hours

=> 240 / 8

=> $ 30 Per Hour

5) There is a line formula which is "y = mx + b".

In this, "m" is the slope.

"b" is the y-intercept.

"y" is the y-axis line.

"x" is the x- axis line.

y-intecept means that a point on the graph which has the x value as "0" and y value as anything.

Slope is rise / run.

So, by looking at the graph, we can tell that the y-intecept is (0,0). So, the y-intercept is 0.

Slope = y2 - y1 / x2 - x1

=> 10 - 0 / 2 - 0

=> 10/2

=> 5

So, the equation looks like y = 5x.

6) This is the same question as the above one.

=> Y - intercept = (0,5)

So, the y-intecept is +5.

Now, the equation is  y = mx + 5

=> Slope.

=> Slope of the points (0,5) and (2,8).

We used points (2,8) because the line passes through these points.

=> 8 - 5  /  2 - 0

=> 3 / 2

So, the equation is y = 3/2x + 5

7)  By looking at Rebecca's equation, we can tell that her hourly pay is $9.25.

For Andrew's hourly pay, we need to find the slope of the points.\

Slope = y2 - y1  / x2 - x1

=> 57 - 47.5  /  6 - 5

=> 9.5 / 1

So, the equation for Andrew looks like  y = 9.5x

So, we can tell that Andrew's hourly pay is 9.5.  Rebecca's hourly pay is 9.25

both equations and proportions are better.
