The slope of a linear function is given by the formula:
Where m is the slope, (x1,y1) and (x2,y2) are two points on the line. We can find these values in the given table.
By replacing (-1,-2) and (0,-3) we can find the slope:
The slope is -1.
The y-intercept is the y-value at x=0.
In the table we can see when x=0, y=-3
The y-intercept is -3.
The slope-intercept equation of a line is given by:
Where m is the slope and b is the y-intercept. If we substitute these values we have:
