Vocabulary
Define parallel lines.
Two lines in the same plane that never intersects. Parallel lines have the same slope.
Solve 3x+4y=8
y=3/4x−2
Solve y-8=-3(x+1)
y−2=−3(x−1)�-2=-3(�-1)
parallel lines
coplanar infinite straight lines that do not intersect at any point.
y-y₁=m(x-x₁)
point slope form
Define y-intercept
the y-coordinate of point where a graph crosses the y-axis.
Solve 2y-6=-6x
y=−3x+3
Solve y=2(x+3)
y=2x+6
perpendicular lines
y = mx+b
slope intercept form
Define reciprocal
the reciprocal of a number is 1 divide by that number.
Solve -14x+y=7
y=14x+7
y-y1=m(x-x1)
y=3x-5
reciprocal
another way to state the definition is as follows: the product or reciprocal is 1.
3/4.4/3=1
standard form
Ax+By=C
Define perpendicular lines
lines that intercept to form right angels. Two lines are perpendicular if the product of their slopes is -1.
Solve -2(2x+y)=28
y=−2x−14
Y-Y1=m(X-X1)
Y-3=1/3(X-2)
standard form of a linear equation
integers are rational numbers with no fractional or decimal part

Do you smell carrots?- stfu its funny
the slope-intercept form of linear equations is y=mx+b.
Solve 9x+35=-5y
y=−9/5x−7
Y-3=-2/3(X+1)
Y+2=1/2(X-3)
point slope form
y-y₁=m(x-x₁)
