what is slope intercept form?
y = mx + b
100
what is standard form?
Ax + By = C
100
what is point slope form?
y - y1 = m ( x - x1)
100
what is direct variation?
y = kx
100
what is absolute value?
the distance from zero
200
find the slope and y - intercept of y = -1/2x - 4
slope -1/2 y intercept -4
200
find the intercepts of 14x + 28y = 28
x = 2 and y = 1
200
what is the point and the slope of y - 3 = -2/3 ( x + 5)
slope = -2/3 point ( -5, 3)
200
what is the constant of variation?
k = y / x or y:x
200
where is the vertex of y = | x + 4|
x = -4
300
find the slope of the line through ( -4, -3) and ( 7,1)
4/11 or 0.363636....
300
find the x and y intercepts of -1/2x - y = 3/4
x = - 3/2 or - 6/4 y = - 3/4
300
write in point slope form the equation of the line through ( -10, 3) and ( -2, -5)
y - 3 = -1 ( x +10) or y +5 = -1( x +2)
300
does y vary directly with x 3y = 2x if so find the constant of variation
yes y = 2/3x
300
where is the vertex of y = |x + 3| - 5
( -3, -5)
400
find the slope of the line through ( 2/3, 4/7) and ( 2/3, 11/7)
undefined
400
write in standard form the equation of the line with slope = 3 and ( 1, 5)
3x - y = -2
400
write in point slope form the equation of the line through ( 0, -1) and ( 3, -5)
y + 1 = -4/3 ( x - 0) or y + 5 = -4/3 ( x-3)
400
does y vary directly with x in 2y - 1 = x if so what is the constant of variation.
no
400
how do you know if the graph opens up or down
up there is no negaitve in front of the abs value down there is a negative in front of the abs. value
500
transform this into slope intercept form 3x + 2y = 12
y = -3/2x + 6
500
rewrite in standard form y - 2 = 3 ( x - 7)
-3x + y = -19
500
write an equation in point slope form through ( 1, 9) and (6, 2)
y - 9 = -7/5 ( x - 1)
500
find the missing value for y = 4 when x = 3 find y when x = 6
y = 8
500
write an absolute value equation for the vertex of ( 7, -5)
y = | x -7| - 5
