Answer:
see below
Step-by-step explanation:
The point-slope form of the equation of a line is ...
y -k = m(x -h) . . . . . . . . line of slope m through point (h, k)
Comparing this form to the equation you are given, we can match parts to see that ...
That is, your line has a slope of -3/4 and goes through the point (-4, -2).
__
To graph this line, it is often convenient to start with the given point, then use the slope to find another point. The given point is (-4, -2).
The slope is "rise"/"run". A slope of -3/4 tells you the line will drop 3 units for each 4 units it moves to the right. If we add 4 to the x-value of the given point, we get 0. If we add -3 to the y-value of the given point, we get -5. So, another point on the line is (0, -5).
Knowing these two points, you can draw the line through them to graph the equation.

How I got there
Total number of degrees 180
add 59 + 91 = 150
180 - 150 = 30
30 divided by 2 = 15
Note that Cheryl wants to find the number of hours <u>seventh grade boys and girls</u> spend on homework each week.
There are multiple causes of a biased sample. Two of the most obvious ones I find are:
1. She's surveying <u>girls</u>, but she is trying to get data on the number of hours <em>all</em> seventh graders (boys <em>and</em> girls) spend.
2. She's surveying 50 girls from the <u>entire school</u>, although she is trying to get data on seventh graders only.
