Question

Let f be a linear function with f(-4)-f(3)/7=5/3. find f(5)-f(1)/4

Answer 1

Answer: slope is -5/3

Explanation:

f(-4)-f(3)/7=5/3. find f(5)-f(1)/4

...

We see the slope of this linear function -5/3

If you notice slope=[f(-4) - f(3)]/(-4 -3) = - [f(-4)-f(3)/7 ] = -5/3

so f(5)-f(1)/4 = [f(5)-f(1)] /(5 - 1) = -5/3
