Slope: m= change in y = y2-y1

change in x x2-x1

Slope-intercept form: y=mx+b

Point-slope form: y-y1=m(x-x1)

Standard form: Ax+By=C; where A is a positive value

Find the slope of the points. Reduce to lowest terms.

Answer: _______________

Graph the following equations and inequalities on a coordinate plane, shading the solution set where necessary.

Go to ‘insert’ and ‘shapes’. Choose the circles for the points and the lines to connect the dots. Use the arrows to represent the shading.

For example:

15. y= 4x-2

Calculations:

16. 2x+5y=10

Calculations:

17. x=3 and y=6

Calculations:

18. 3x+5y ≤ 15

Calculations:

19. y < -2x-3

Calculations:

20. x > 4 and y ≤ -1
