Answer:
The slope-intercept form:
Step-by-step explanation:
-To get the slope-intercept equation, you first need to find the slope by using this equation (starting counting from the first point, to the second point) in order to get the slope. After you have the slope, you need to find the y-intercept ( y-intercept is where the line crosses the y axis of the graph, basically). So, to find that, you need look for the point that only crosses the y axis to get the y-intercept. After you have both the slope and y-intercept, you put it in slope-intercept form:
The two points I found from the following graph are:
and
Trick: Since the line of the graph shows that it is down (not up), Start counting down from point to point
. Then, find the y-intercept:
Use it to create a slope-intercept form:
(where
represents the slope and
represents the y-intercept)
So, therefore the slope-intercept form is .
Answer:
and
Step-by-step explanation:
we have
we know that
Compound inequality can be divided into two inequalities
so
rewrite
and
therefore
An equivalent form of the compound inequality is

Answer: 242 students do not like football or baseball
Step-by-step explanation:
The total number of students that were surveyed about their preferences of sports is 412. The Venn diagram is shown in the attached photo.
If 45 students like both sports, then the number of students that like football only would be
115 - 45 = 70
Also, the number of students that like baseball only would be
100 - 45 = 55
The number if students that like at least one of the sports is
70 + 55 + 45 = 170
Therefore, the number of students that do not like football or baseball would be
412 - 170 = 242
