graph f(x)=4/5x-4

Question

Graph 

f(x)=4/5x-4

Answer 1

f(x) =( 4/5)x - 4

 

let's try f(0) = (4/5)(0) - 4 = -4        -------> so one point is (0, -4)

let's try f(5) = (4/5)(5)  - 4 = 4 - 4 = 0 -----> other point is (5, 0)

 

plot these points on a graph paper and connect points with a straight edge.
