Answer:
y = -2x + 5
Explanation:
You use the equation y = mx + b, where m is the slope and b is the y-intercept. We see that the line hits the y-axis at 5, so that will be your b. To find the slope, use
. You have to go down 4 and right 2, so your slope will be
which simplifies to -2. Hope this helps!
