Question 409915: 1) What is the equation of the line whose y-intercept is 3 and slope is 1?
y = x - 3
y = x + 3
y = 3x + 1
2) What is the slope of a line parallel to the line whose equation is y - x = 5?
-1
1
5
3)What is the equation of a line that passes through points (-1, 2) and (5, 2)?
y - 2 = 0
x - 2 = 0
y - x - 2 = 0
4)What is the equation of a line with a slope of -2 and a y-intercept of 8?
x + 2y - 8 = 0
2x + y - 8 = 0
2x - y + 8 = 0
5)What is the equation of the line that passes through the point (1, 1) and has a y-intercept of 2.
x - y + 2 = 0
x + y - 2 = 0
x - y - 2 = 0
