I need help on most of my test.

y = 2x - 7

Step-by-step explanation:

The standard form of equation of a line is y - mx+ b

m is the slope

b is the y- intercept

Using the coordinates (3, -1) and (2, -3)

m = y2-y1/x2-x1

m = -3+1/2-3

m = -2/-1

m = 2

Since the line cuts the y axis at y = -7, hence the y intercept is -7

Substitute m = 2 and b = -7 into the equation y = mx+b

y = 2x + (-7)

y = 2x - 7

This gives the required equation
