Aline passes through ( 2, -1) and (4,5)
which answer is the equation of the line ?
a) -3x + y = -7
b) -3x + y = 17
c) -3x + 5y = 13
d) -3x + 5y = -13

If δmtv is reflected across the y-axis, what are the resulting coordinates of point m? a) (-2, 5) b) (-5, 2) c) (5, -2) d) (-2, -5)

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125

If 5x - 2 = -12, then x = a) -50 b) -4.4 c) -2.8 d) -2
