How do you write an equation of a line going through (d, 0) parallel to y = mx + c?
The point-slope formula can be used to find the equation being asked for in the equation.
First, determine the slope. Because the problem is asking for a parallel line it will have the same slope as the line given in the problem. And because the line given in the problem is in slope-intercept form we can extract the slope directly from the given equation.
The slope-intercept form of a linear equation is:
Therefore the slope we will use to answer this question is
The point-slope formula states:
Substituting the point from the problem gives:
Or translating to the more familiar slope-intercept form:
