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 
.
Choices B, C, and D are incorrect and may result from misinterpreting the slope-intercept form of an equation of a line.
