The slope is 2/3, and the y-intercept is 4. In slope intercept form, the equation is y=2/3x+4
There are 12 wheels on 4 tricycles.
So the man's age is divisible by 3, 5, and 7 but not by 2, 4, 6, or 8.
3 * 5 * 7 = 105
105 is not divisible by 2, 4, 6, or 8.
Not sure if any lower ages are there, but since the man is 105 years old, you would receive $105.
Your intention with the wording "consecutive integers of 12 feet" is not clear. Shown are triangles with sides 12 and 13 (a nice Pythagorean triple) as well as 11 and 12.
I think it might be 7 don't know what answers you may have but its a guess
