Scott works as a delivery person for a shipping company the graph shows a linear model for his delivery times on different days. the points are (21,3) and (12,6) what is the equation of the line written in point-slope form and slope-intercept. show how u determined ur equation and show ur work

Point 1 is (21,3); Point 2 is (12,6)

The general equation for the slope-intercept form is

where m is the slope. To compute for the slope,

To determine the y-intercept, we replace x and y with values from any of the two points. In this case, I'll use P1.

b = 10

Thus, the slope-intercept form is

The general equation for the point-slope equation is

Substitute any of the points. In this case, I'll use P2, just to be different. It would yield the same answer when you simplify it:)
