1.) What is the prediction for the percent of people that are exercising during the 30th week after the start of the year?
2.) Is this value above or below the actual value?
3.) Estimate the real value for the last week of the year using a whole number.
4.) Is the prediction above or below the actual value?

-6 is the correct option from the above given options

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.

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.
