I can’t find the answer tried twice probably easy for others

y=-x-2

Slope intercept form is written as y=mx+b, with m being the slope and b being the y intercept.

The slope is negative one. To find the slope, use the formula y1-y2/x1-x2. When you substitute, you may get -4-1/2-(-3). When you solve it, you get -5/5, or -1.

To find the y intercept, look where the line crosses the y axis (vertical line). In the graph, it crosses as -2. Substitute these numbers into the equation and you get y=-1x-2 which can be simplified to y=-x-2.

Iam not sure , but probably 750 or 7.5
