Answer:

  • slope m = 5
  • y-intercept b = -15

Explanation:

You want the slope and y-intercept of the line shown in the graph.

Y-intercept

The line crosses the y-axis at y = -15.

The y-intercept b is -15.

Slope

The two marked points show the line has a "rise" of 0 -(-15) = 15 for a "run" of 3 -0 = 3. The slope is ...

m = rise/run = 15/3 = 5

The slope m is 5.

Additional comment

The line rises 1 grid square for each 1 grid square to the right. However, each grid square is 5 units in the vertical direction and 1 unit in the horizontal direction. Though the squares are ...

vertical/horizontal = 1/1

the units are ...

vertical/horizontal = 5/1 = 5.

One always needs to check the scale of the graph when using grid squares to compute the slope.
