A gymnast wants her average score after 3 events to be between 9.0 and 10. If she scores an 8.7 and 9.1, what possible values for the third event will make her average between 9.0 and 10?

78.59 is the mean

step-by-step explanation:

step-by-step explanation:

this equation is in point-slope form.

where,

using this equation you can gather a point and the slope, which gives you enough information to draw a line. transform the equation to standard form to start.

the equation is now in standard form, we have a point, as well as the slope:

point: (0, -6)

slope: -2

plot (0,-6), then simply rise/run with the provided slope of -2, once you feel you have a comfortable amount of points - draw a line.
