Answer:
y-4=0
Step-by-step explanation:
its the only that doesn't have a x?
In order to reach the total cost of $128, you need to find the number of hours the company cleaned. The equation to do so would be
30x+ 8 = 128
If you subtract 8 from both sides and then divide by 30 you'll find that x=4.
Answer:

Step-by-step explanation:
Hi there!
Slope-intercept form:
where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x=0)
<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>
where two points that fall on the line are
and 
On the graph, two points are highlighted for us: (0,-4) and (2,2). Plug these into the formula:

Therefore, the slope of the line is 3. Plug this into
:

<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>

Recall that the y-intercept occurs when x=0. Given the point (0,-4), the y-intercept is therefore -4. Plug this into
:

I hope this helps!
