In the xy-plane, a line has a slope of 6 and passes through the point . Which of the following is an equation of this line?
A
B
C
D
Correct answer: A
Explanation
Choice A is correct. The slope-intercept form of an equation for a line is , where m is the slope of the line and b is the y-coordinate of the y-intercept of the line. It’s given that the slope is 6, so . It’s also given that the line passes through the point on the y-axis, so . Substituting and into the equation gives .
