Answer:
y = -2x + 3
Explanation:
The three is the y-intercept, so when x=0, y will equal 3. (0,3)
The slope is negative (-2x), because the minus is present infront of x. So the line's going down.
And we can confirm that it's the function
y = -2x + 3 by letting one point in the line from the graph enter the function.
For example (1,1)
1 = -2x + 3. (let y = 1.)
1 = -2(1) + 3 (let x = 1)
1 = 1
so we can see when we let 1 = -2(1) + 3 it equals the y value on the line.
