Answer is graph A
Step-by-step explanation
We know he makes $2560 for 80 hours worked. To find his rate of pay,
2560 divided by 80 hours = 2560/80
= $32 per 1 hour of work
So your graph will show
at 1 hour (x axis) the line ( y axis) will be at 32
at 2 hours the line will be at 64
at 3 hours the line will be at 96
And so on
Graph B and C are straight lines so they are not showing a rate of change or increase
Graph D starts at $80 on the pay line, which is not part of this equation
