1. Which linear equation has a slope of 3 and a y-intercept of –2?
y = 3x + 2
y = 3x – 2
y = –2x + 3
y = –2x – 3
2.Adriana writes the equation y = 2x + 4 to represent a line on a graph. Henry writes an equation that has a y-intercept that is 1 unit lower on the graph but has the same slope as Adriana’s line. Which is Henry’s equation?
y = x + 4
y = 3x + 4
y = 2x + 3
y = 2x + 5

1) the answer is y=3x-2
Explanation: the slope is the number on the left side of x and the y-intercept is on the right side of x.

2) the answer is y=2x+3
Explanation: Henry's slope is the same as Adriana's (2/1). Henry's y-intercept is one lower than Adriana's, so you subtract (4-1=3) - Henry's y-intercept is 3.
