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
