Answer:
- slope = 2
- y-intercept = -3
- equation: y = 2x -3
Step-by-step explanation:
slope
The line goes up 2 grid squares for each 1 grid square to the right. The slope is ...
m = rise/run = 2/1 = 2
intercept
The y-intercept is where the line crosses the y-axis. That point is marked -3, so the y-intercept is ...
b = -3
equation
Use the found values of m and b in the slope-intercept form:
y = mx + b
y = 2x +(-3) . . . . . put 2 where m is; put -3 where b is
y = 2x -3 . . . . simplified
