I’m not sure how to work this out could someone help me please

Remember slope is the rise over run.

Step-by-step explanation:

So it would be y=-4x+1.

y=4/3x+4

Step-by-step explanation:

Slope intercept form is y=mx+b

m is always the slope and b is always the y-intercept

These are the steps to find the equation of any graph:

First, fine the y-intercept. That's the point where the graph crosses the y-axis (the line going up and down). So b=4

Then, to find the slope, you literally count how many you go up or down (rise) and left or right (run) to get to another point. You can choose any point on the graph you want. I'll choose the point (-3,0). So you start at (0,4) and you go down 4 and left 3 to get to the second point. So the slope = rise/run = -4/-3 so m=4/3

Now plug the slope (m) and y-intercept (b) into the slope-intercept equation

y=mx+b

y=4/3x+4

Follow these steps for any similar problem, just start with the y-intercept and count the rise over run to find the slope, then plug in the slope and the y-intercept.
