Answer: y = -2x + 5........ -2 in the first box and 5 in the second. :)
Step-by-step explanation: Ok...
From right to left (how you read graphs), the line is going down, so the slope (that first box in the problem) is going to be negative.
It falls 2 units and runs 1 unit. -2/1 is -2. The first box is -2.
The second box is looking for the y-intercept, or where the line hits the vertical line (the y-axis) which is where x is 0. It hits at 5 units up. The second box is 5.
