Slope-Intercept Graphs

Find the slope-intercept equation

• y = 2x + 3

• y = -2x +3

• y = ¹/₂ x+3

• ^{y = -1}/₂ x+3

What is the equation of the line given the following information?

• y = -4 - 3/4x

• y = -3/4x - 4

• y = -4x - 4

• y = 3/4x + 4

What is the y-intercept of this line?

• none

• 0
