100
Which of the following ( there could be more than one) is a solution to the line y = -2x + 5: (0, -5) (1, 3) (-2, 9) (2.5, 0)
(1, 3) (-2, 9) (2.5, 0)
200
What is the definition of the y intercept?
The point where the line crosses the y axis.
200
What is the point slope form of a line with a point at (2, 5) and a slope of 3?
y - 5 = 3 (x -2)
200
What is an equivalent standard form equation to this one: 2x + 7y = 5
Need to check
200
What is the slope intercept form of a line with the standard form 5x - 2y = 10?
5x - 2y = 10 +2y +2y 5x = 2y + 10 -10 -10 5x - 10 = 2y so (5/2)x - 5 = y or y = (5/2)x - 5
200

500
What is the correct slope intercept equation for a line with points at (3, 2) and (5, -8)?
slope = 10/2 = 2 y = 5x + b 2 = 5(3) + b 2 = 15 + b -13 = b so y = 5x -13
