The slope of the line passing through (-1,3) and (-4,0) is:

Step-by-step explanation:

first mark your points

(-1,3) (-4,0)

x1 y1. x2 y2

solve with given points using the formula:

y2-y1/x2-x1

=

0-(3)

-4-(-1). = -3/-3 = 1 (slope)

plug slope and one pair of points into (y=mx+b)

(0) = -4(1)+b

=-4+b

4=b

add everything together:

y=x+4

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
