The question requires that the equation should be in the slope-intercept form. The and in this equation are constants. In particular:
would represent the slope of this line (also known as the gradient of this line,) whereas
would be the -intercept of this line.
The question states that the slope of this line is . Therefore, . Thus, the equation for this line should be in the form .
The value of constant could be found using the other piece of information: the point is in this line. In other words, the solution should satisfy the equation .
Substitute into the equation and solve for :
.
.
.
Hence, would be the slope-intercept form of the equation of this line.
