DONT SEND LINK OR FILE THINGS LIKE THAT!!!!!!!!!!!!!

The picture is the line slope

The line slope is -4

I need to find the equation for the line and I can’t find it

It would go something like
Y=__________

It goes y=-4x+????

PLEASE HELP!!!!!

y = -4x + 20

Explanation:

Note that the line goes through the following points:
P_1(0, 20) and
P_2(5, 0). So the slope of this line is


m = (y_2 - y_1)/(x_2 - x_1) = (0 - 20)/(5 - 0) = -4

Now we can write the general form of the slope-intercept equation of the line as follows:


y = -4x + b

To find the value of b, we can use either P1 or P2. Let's use P1:


20 = -4(0) + b \Rightarrow b = 20

Therefore, the equation of the line is


y = -4x + 20
