This back to back stem and leaf plot shows the test scores (out of 100 possible points) for two of mrs. guthery's math classes. the middle column digits are the stems. the column to the left and the column to the right are the leaves.

in class 2, how many students scored lower than 65?

10 students

Slope = -1/2

Y-intercept is y = -1

Equation of the line:

Step-by-step explanation:The slope intercept form is  y = mx + b

Where, m is slope, and

b is y-intercept

We need 2 points to find these. One point is  (-2,0) and second point is (2,-2).

THe formula for slope, m, is m =

Plugging the points, we get the slope to be:

y-intercept is the point where the line crosses the y axis. Looking at the graph, y-intercept is y = -1.

Now we plug slope and y-intercept into the slope-intercept form to get:
