Hi,
You can start by eliminating option A and B because a line is increasing if it goes up from left to right. So now the options are C and D. Then you look at the constant which is +1 or -1. This number is your y-intercept so if you look at the graph, you can see that the graph goes through the y axis at (0,-1). So the answer is D. y=3x-1.
Solving for a gives us: 
Step-by-step explanation:
Solving an equation for a variable means that we have to isolate the variable in the equation
Given equation is:

For isolating a, subtracting c from both sides

Subtracting b from both sides

Hence,
Solving for a gives us:
