The black points are the y-intercepts and and purple ones are the x-intercepts.
28 is 4 times 7. So, to make the fraction equal you must also multiply the numerator by 4
4x3 =12 so the new fraction would be 12/28
First, do the minimum: multiply both sides by 9/5, so the left side is -54 and the right side is f-32. Now add 32 to both, and you get the minimum of -22 degrees F.
Then, do the same for maximum, by plugging in 130 as c, multiply 9/5 to get 234, then add 32 to get 266 degrees.
The answer is -22 and 266.
It would be 0.2
