It wants you to write the answer in slope intercept form
y = mx + b
m is the slope ()
b is the y-intercept (where the line intersects the y axis)
The rise is 1
The run is -4 (this is negative because it runs from right to left)
^^^Both of these can be seen labeled in pink on the graph below
Slope: = -0.25
^^^This has a negative slope because the line is decreasing from left to right
Y - intercept: (0, - 6) <<< b will just be -6
^^^Can be seen labeled in green on the graph below
We know that m (slope) is (aka -0.25)and that b is -6. You can plug this into the equation y = mx + b:
y = x - 6
OR
y = -0.25x - 6
Hope this helped!
