Answer:
Option C. $798
Step-by-step explanation:
we know that
The total hours worked the last two weeks ( 80 hours) multiplied by $7 per hour plus the 10% commission on her sales ($2,384) is equal to the amount of money that Sandy earned for those two weeks
Remember that
so
Okay, let's see...
The problem is asking for a linear equation most likely in the form of y=mx+b
y is another way to say f(x)
<em>m = slope </em>
<em>b = y intercept </em>
Let's start with the y intercept first.
Y intercept means ' When does the line touch (intercept) the y axis.
In this case, if you look at the graph, the line <em>touches </em>the y axis at -1.
-1 will replaces b
To find the slope we are going to take 2 precise points from the graph.
Lets use <em>(0,-1)</em> and <em>(-6,4) </em>
To find the slope, we're going to use
4 - (-1) / -6 - 0
Solve, our slope is 5/-6
That is our m
Our final equation is
PARALLEL slopes always have the same slope no matter what because they are parallel
