1/2p + 67 = 68
p=2
-4(5x-8)= -108
a = 7
4w + 2 - w = 7 - 2w
w=1
What is the slope of the equation
y = 1/2 x + 7
1/2
How many degrees are in a Triangle?
180 degrees
(x + 2)/4 =-5
x = -22
-3(2a - 3) + 1=-20
a = 5
2(x+3) = 3x + 6
x = 0
Graph the equation
y = 2x + 1
(remember y = mx + b)
m is the slope / b is the y-intercept
first point at ( 0, 1) then count up 2 and right 1
Draw a pair of parallel lines and a pair of perpendicular lines
Parallel lines = two lines that never intersect (in the same plane)
Perpendicular lines = two lines intersecting that form a 90-degree angle (the 90-degree angle must be marked to get the points)
1/5x - 12 = 3
x = 75
-168=-7(-5 + 3x) - 8x
x = 7
