Graph the following lines on the coordinate plane:

Y = mx+b is slope intercept form

m is your slope, the number that m is tells you how many times you go up and over (rise over run)

b is your y intercept, this number tells you where your line should pass

a. y = 2x +1
plot a point at 1 for y, then go up 2 over 1 and draw a line

2 also means 2/1 so you go up twice and over once

b. y = -3x -2
plot a point at -2 for y, and then go up 3 and over 1 but since it’s a -3 you go down 3 over 1

the - shows that your line should be facing the left because it’s a negative slope

c. and d. are hard to see so i can’t tell if that is a = sign or a - sign

but if it’s a = sign follow the steps like the other problems if it’s a - sign solve for y so it turns into slope intercept form then follow the steps like the other problems

B.the point lies directly on the regression
