Question

At 78°F, a certain insect chirps at a rate of 106 times per minute, and at 81°F, they chirp 112 times per minute. Write an equation in slope-intercept form that represents the situation.

Answer 1

y = (1/2)x + 25 or y = 0.5x + 25

Explanation:

I used a online calculator that is reliable.

Answer 2

y=2x-50

Explanation:

`m=(y^2-y^1)/(x^2-x^1) = (112-106)/(81-78) =(6)/(3) =2`

slope-intercept formula(substitute 81 for x, 112 for y, and 2 for m:

y=mx+b

112=2(81)+b

112=162+b

Then subtract 162 from both sides, and b=-50

Plug in all numbers into original equation

y=mx+b m=2 b= -50

So u get y=2x-50
