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.
