Calculate the slope between the following points: (2,1) & (4,5)
The slope is 2.
1/2 x + 1/6 =0
x = -1/3
(x + 2)(x + 4)
x2 + 6x + 8
Calculate the slope between the following points. (-2,-1) & (7,8)
The slope is 1.
2x - 18 = -3x + 33
x = 9
x2 + 12x + 35
(x + 7)(x + 5)
If three consecutive even numbers have a sum of 84, what is the largest number?
The largest number is 30.
If the y-intercept of a line is -4 and the slope is 6, what is the equation of the line in slope intercept form.
y = 6x - 4
(-2x + 5)(5x - 1)
-10x2 + 27x - 5
Spencer, Neal, and Claire go lastertagging. Neal gets five more than two times the number of kills as Spencer. Claire gets twice as many kills as Neal. If the three of us had 92 kills altogether, how many kills did Claire get?
Claire got 54 kills.
Graph the following line. y = -2x + 5
x-int:2.5
y-int:5
x2 - 2x - 15 = 0
x = 5 or x = -3
x2 - 16x - 36
(x - 18)(x + 2)
Given a line passes through the y intercept of -1, and goes through the points (1,2) and (3,8), what is the equation of the line?
y = 3x - 1
x(x - 9) = -18
x = 6 or x =3
x2 - x - 12
(x - 4)(x + 3)
