I'm very much stuck here

Answer:
y = 3/4x-1
Step-by-step explanation:
The y intercept ( where it crosses the y axis) is -1
The slope intercept form of the equation is
y = mx+b where m is the slope and b is the y intercept
y = mx-1
The only equation in this form is a
y = 3/4x-1
We also know that the slope is position, since the line goes up from left to right ( up 3 over 4)
