When you find the value of an expression you are doing this skill.
What is evaluate an expression?
This form has the y-intercept (0, b) and the slope
What is Slope Intercept Form? y=mx+b
y=3x - 5
What is slope, m=3, and the y-intercept (0, -5)?
This form has a point (x1, y1) and the slope
What is Point Slope Form? y - y1 = m(x - x1)
What is the x-intercept (4, 0) and y-intercept (0, 2)?
5x
What is the product of 5 and x. "5x" also says 5 times x?
a + 0 = a
What is Identity Property of Addition? or What is the Zero Property of Addition?
Standard Form looks like this?
What is Ax + By = C?
y - 5 = 2(x - 7)
What is the slope, m=2, and the point (7, 5)?
(a - b)
What is the difference of a and b?
The x-intercept (x, 0) and y-intercept (0, y) can be found directly using this form
Tell me any equation that is parallel to y=5x-4
Any equation y=5x+any number?
5 > x
What is x is less than 5? {Note: you must rewrite the expression as x<5, from left to write.}
4>y+1, integers only please
What is y is less than 3 or y<3.?
Write a parallel line to y=2x + 10 through (-3, 5)
What is
y-5=2(x+3)
-4<=x+1<5
What is "sum of x and 1" is greater than or equal to the -4 and less than 5"? OR "x+1"
Solving the equation (example: )uses the Property of Equality which is also know as performing the I_ O_
What is the Inverse Operation?
Replacing a value for a variable in an equation or expression.
What is substitution?
The product of the LCM and GCF for 20 and 12.
Product = (LCM)(GCF)
20: (1)(2)(4)(5)(20)
12: (1)(2)(3)(4)(6)(12)
20:40:60
12:24:36:48:60
7/2-3/5x=1
What is
x=25/6
Parallel lines have the same slope, perpendicular lines have {Hint give me an example}
opposite reciprocal.
{example: m = 2 and
m=-1/2
)
Write a perpendicular line to y=-3x+4 through the point (1, 5)
What is
y-5=1/3(x-1)?
