1.Write the equation of a line with a slope of 3 and a y-intercept of 1.


y = x + 3

y = 3x + 1

3x + y = 1

x + 3y = 1

2.Write the equation of the line that passes through (1, 3) and has a slope of 2 in point-slope form.


y – 1 = 2(x – 3)

y – 3 = 2(x – 1)

x – 1 = 2(y – 3)

x – 3 = 2(y – 1)

3.Write the equation of the line that passes through (–2, 6) and (2, 14) in slope-intercept form.


y = 2x – 2

y = 2x + 10

y = 0.5x + 7

y = 0.5x – 4
