Slope

100

What is the formula for the point-slope form of a linear equation?

y - y₁ = m(x - x₁) 

200

Find the slope between these two points:

(4,8) and (6,-12)

m= -10

300

Write an equation of a line that is parallel to 

y=-2x+3

Any line where m= -2

400

Write an equation for a line that is perpendicular

to y= 1/4x+5

Any line where m=-4 or -4/1

500

Solve this equation for y: 3x + 4y = 10

y = -3/4 x + 5/2

Graphing

100

Find the slope: y = 3x + 5

3

200

Algebra: What is the slope intercept formula?

algebra: y=mx+b

300

Write an equation for a line in point slope form that has a slope of -5 and passes through the point 3,-4.

y+4=-5(x-3)

400

Is this equation in standard form?

-3x+6y=9

Why or Why not?

No because the first term or term with x has a negative in front the 3.

500

Algebra: Write the standard form of the linear equation for the line passing through (3,9) (5,4) 

Algebra: y=-5/2x+33/2
