Answer:
y = -1.5x - 3
Step-by-step explanation:
The slope-intercept form of a line is y = mx + c where m is the slope of the line and c is the y-intercept of the line.
To find the slope of a line, you need to find the 
between two of the points. I will be using the points (-2, 0) and (0, -3).
= 
= 
= -1.5
Now based on the graph, we see that the y-intercept is -3. Thus, the entire equation of the given line is: y = -1.5x - 3
Let the marks of the students in class 1 be
the average of these 12 marks is 90, so
which means
similarly, let
be the marks of the students in the second class,
so
which means
The 32 students averaged:
Answer:
5 is greater than y-8 since 5 is positive it + in the begging +5 while - 8 is less than 0 because it has - in the begging
