Question

3. What is the equation of the line graphed below?

y= -5/2x + 2
y=-5/2x -2
y= 5/2x - 2
y= 5/2x + 2

Answer 1

2nd option: -5x-2

Explanation:

Since we can see the graph intercepts the y-axis at -2 the equation must end with -2 using the formula:

`y=mx+c`

Since it has a negative gradient as the graph goes from left to right, the gradient is -5/2
