Question

At 109°F, a certain insect chirps at a rate of 77 times per minute, and at 117°F, they chirp 101 times per

minute. Write an equation in slope-intercept form that represents the situation.

The equation that represents this situation is

Answer 1

y=3x-250

Explanation:

Slope intercept form: y=mx+b

Step 1) to find slope, use (y2-y1)/(x2-x1)

(101-77)/(117-109) = 3

m = 3

Step 2) determine y-intercept (b)

109 * 3 = 327

77-327 = -250

b=-250

y=3x-250
