#### Answer

part a: (0,2)
part b: (-3,0)
part c: x=3
part d: y=2.75

#### Work Step by Step

part a: By looking at the graph, the y-intercept is where the line intersects the vertical axis. That would be 2. Written in proper form as an (x,y) coordinate, the answer would be (0,2).
part b: By looking at the graph, the x-intercept is where the line intersects the horizontal axis. That would be -3. Written in proper form as an (x,y) coordinate, the answer would be (-3,0).
part c: We know that we are looking for the x value that makes y=4 true. (x,4) is a better way to visualize this. At y=4 on the graph, the line reaches 3 on the x-axis.
part d: We know that we are looking for the y value that makes x=1 true. (1,y) is a better way to visualize this. At x=1 on the graph, the line reaches about 2.75 on the y-axis.
