Lesson 2:Linear Equations

Vocabulary

100

Define parallel lines.

Two lines in the same plane that never intersects. Parallel lines have the same slope. 

200

Define y-intercept

the y-coordinate of point where a graph crosses the y-axis.

300

Define reciprocal 

the reciprocal of a number is 1 divide by that number.

400

Define perpendicular lines 

lines that intercept to form right angels. Two lines are perpendicular if the product of their slopes is -1.

500

define slope-intercept form

the slope-intercept form of linear equations is y=mx+b.

Slope-intercept form

100

Solve 3x+4y=8

y=3/4x−2

200

Solve 2y-6=-6x

y=−3x+3

300

Solve -14x+y=7

y=14x+7

400

Solve -2(2x+y)=28

y=−2x−14 

500

Solve 9x+35=-5y

y=−9/5x−7

Point-slope form

100

Solve y-8=-3(x+1)

y−2=−3(x−1)�-2=-3(�-1)

200

Solve y=2(x+3)

y=2x+6

300

y-y1=m(x-x1)

y=3x-5

400

Y-Y1=m(X-X1)

Y-3=1/3(X-2)

500

Y-3=-2/3(X+1)

Y+2=1/2(X-3)

vocabulary 2

100

parallel lines 

coplanar infinite straight lines that do not intersect at any point.

200

perpendicular lines

Perpendicular lines are lines that intersect at a right (90 degrees) angle.

300

reciprocal

another way to state the definition is as follows: the product or reciprocal is 1.

3/4.4/3=1

400

standard form of a linear equation

integers are rational numbers with no fractional or decimal part

500

point slope form 

y-y₁=m(x-x₁)

what form is shown /do u know how

100

y-y₁=m(x-x₁)

point slope form

200

y = mx+b

slope intercept form

300

standard form

Ax+By=C

400

What did one snowman say to the other?

Do you smell carrots?- stfu its funny

500

What is a sea monster’s favorite snack?  

 Ships and dip. hahaha
