问题 What is the y-intercept of the line with the equation 2y=4x+6?
选项
答案 First, rearrange the equation into the slope-intercept form by isolating y on the left side; divide both sides by 2: y=2x+3 You know that in the slope intercept formula, y=mx+b, b is the y-intercept. Because b=3, the correct answer is 3.
