问题 What is the y-intercept of the line with the equation 2y = 4x + 6?

选项

答案 3

解析 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.
