Explanation:
If both lines are parallel, then their slopes must be equal.
For the line PQ, the slope is:
Slope of PQ = </span> --- (1)
For the line P'Q', the slope is:
Slope of P'Q' =
Slope of P'Q' = --- (2)
As (1) = (2), hence the lines are parallel and their slope is (Option A).
Explanation:
If both lines are parallel, then their slopes must be equal.
For the line PQ, the slope is:
Slope of PQ = </span>
For the line P'Q', the slope is:
Slope of P'Q' =
Slope of P'Q' =
As (1) = (2), hence the lines are parallel and their slope is
So, we will be using point-slope form to construct this equation.
Point-slope form's general formula is as follows:
M is the slope,
Y₁ is the Y-coordinate of the point
X₁ is the X- coordinate of the point.
So, our slope is 3 (since the equation is given in slope-intercept form)
Our Y₁ is 7 and out X₁ is 4
So, now we just plug our numbers into the equation.
There's your equation.
Hope this helps!
