Question

Which equation represents the graphed function?

O-3x + 2 = y
0 x+2=y
ox-3=y
O 2x - 3= y

Answer 1

y = 3/2x -3

Explanation:

The general equation of a straight line is;

y = mx + b

where m is slope and b is the y-intercept

Here, we can see that the graph intercepts the y-axis at the point y = -3

So b = -3

To get m, we can substitute any other point values on the plot

We can select (2,0)

So we have;

y = mx -3

0 = 2m -3

2m = 3

m = 3/2

so;

y = 3/2x -3
