What are the three following equation's general forms?
Slope-Intercept
Standard
Point-Slope
Slope-Intercept: y = mx + b
Standard: Ax + By = C
Point-Slope: (y - y1) = m(x - x1)

What is two numbers is the square root of 32 in between?
5 and 6
Find the y-intercept of the equation
-4 + y = 6x
4
Solve the following equation for y
-6x + 2y = 9
y = 3x + 4.5
Convert into Standard Form
y = 2x + 3
-2x + y = 3
y = -4
2y + 6 = x
(-2,-4)
Which number has the greater absolute value?
-7 or 1.3?
-7
Absolute value = 7
Write the slope-intercept equation for a line with a slope of -1 and a y-intercept of 6.
y = -x + 6
Solve the following equation for y
1 - y = 3x
y = -3x + 1
Convert into Slope-Intercept Form
5x - y = 9
y = 5x - 9
y = 1.5
-2x - y = -1.5
(0,1.5)
5.6 divided by 0.8 = ?
7
Find the slope of the equation
4x + 2y = -14
-2
Solve the following equation for y
2(x + 2y) = 8
y = -0.5x + 2
Create an equation in Point-Slope Form for a line that goes through the point (2,4) and has a slope of -3.
y - 4 = -3(x - 2)
y - x = 5
y + 2x = 8

Which car will travel further?
Car A is traveling 57 mph for 3 hours.
Car B is traveling 43 mph for 4 hours.
Car C is traveling 100 mph for 1.5 hours.
Car A = 171 mi.
Car B = 172 mi.
Car C = 150 mi.
Write the slope-intercept equation for a line that has a y-intercept of -3 and passes through the points (1,-1) and (2,1).
y = 2x - 3
Solve the following equation for y
4 + 3(y - 3) = 6x + 13
y = 2x + 6
Convert into Standard Form
1.5 + y = -x
x + y = -1.5
OR
1.5 = -x - y
y - x = 2
5x + 3y = -2
