Will it graph 100- What are the two pieces of information you need to graph a linear equation?
the slope and the y- intercept
100
Find that equation 100- Linear equations should be put into what format?
slope-intercept form (y=mx+b) or solve for y
100
Parallel/ Perpendicular for 100- If two lines are parallel, how what is true about their slopes?
They have the same slope
100
Factoring Polynomials 100- Factoring is the opposite of what?
Multiplying, usually from distribution
100
Solving Quadratic equations 100- What are the 4 steps to solving (factorable) quadratic equations?
Step 1) make sure the equation is set equal to 0. Step 2) Factor it. Step 3) Set each factor equal to 0. Step 4) Solve for each factor
200
Will is graph 200- find the slope and the y-intercept in the following equation: 6x-8y=16
m=-3/4 and y-intercept=-2
200
Find that equation 200- What is the formula for slope between to points?
Slope (m)= (y2-y1)/(x2-x1)
200
Parallel/ Perpendicular 200- If two lines are perpendicular, what is true about their slopes?
There slopes are opposite reciprocals (flipped over with a different sign)
200
Factoring polynomials- What is the first thing you should always look for when factoring polynomials?
The greatest common factor, or gcf, that you can take out of every term.
200
Solving quadratic equations 200- When you solve a quadratic equation, what are you really finding?
The zeros of the function, or the x-intercepts.
300
Will it graph 300- graph this equation y=(-2/3)x-3
I can't draw on here, but it should cross the y- axis at -3 and go down and to the right. The next point should be (3,-5)
300
Find that equation 300- Put this equation in slope-intercept form: 7x-3y=12
y=(7/3)x-4
300
Parallel/ Perpendicular 300- What is the equation for a line is that parallel to y=(3/4)x+1 and has a y- intercept at -2?
y=(3/4)x-2
300
Factoring polynomials 300- Factor this polynomial 3x^2+12x
3x(x+4)
300
Solving quadratic equations 300- How many answers should this equation have? 2x^3+6x^2-18x=0
Three answers, because it's to the third power
400
Will it graph 400- graph the following equation: -5x+3y=-9
y=(5/3)x-3, so it should start with a y-intercept at -3 and the next point should be (3,2)
400
Find that equation 400-What is the equation of a line with a slope of 5 that passes through the point (-3,8)?
y=5x+23
400
Parallel/ Perpendicular 400- What is the equation of a line perpendicular to y= (-4/5)x-6 with a y-intercept of 4?
y=(5/4)x+4
400
Factoring Polynomials 400- Factor this polynomial 2x^3+6x^2-56x
2x(x^2+3x-28)= 2x(x+7)(x-4)
400
Solving Quadratic equations 400- Solve for x: x^2+5=41
x= 6 and -6
500
Will it graph 500- Is this is a linear function? If it is, graph it. If it is not, what kind of function is it? y=(1/x)+2
No, it is not linear. It's a rational function because x is in the denominator.
500
Find that equations 500- What is the equation of a line that contains the points (2,5) and (-3,2)?
y=(-3/5)+31/5
500
Parallel/ Perpendicular 500- What is the equation of a line that is perpendicular to -3x-2y=-8 and contains the point (-9,2)?
y=(2/3)x+8
