<h2>Linear Equations of Vertical Lines</h2>
Linear equations are typically organized in slope-intercept form:
- <em>m</em> = slope
- <em>b</em> = y-intercept (the value of <em>y</em> when the line passes through the y-axis)
However, for vertical line equations, we write them a little differently:
- <em>d</em> = the x-intercept (the value of <em>x</em> when the line passes through the x-axis)
We write equations for vertical lines like this because <em>they might not always have a y-intercept</em>.
<h2>Solving the Question</h2>We're given:
- Line L passes through the x-axis when <em>x</em> = 5
This means that the x-intercept of the line is 5. Plug this into :

Answer:
Step-by-step explanation:
a). Given a parametric equation, we are describing a set of coordinates based on the value of t. The variable t is called the parameter.
b) we have the following equations. x=t y=t^2, so in order for us to know where the object is at t=t' we must replace t with the specific value t'. Hence, when t=0 the object is at (0,0^2) = (0,0) (the origin). When t=6, the object is at (6,6^2) = (6,36).
c). To eliminate the parameter, we replace the parameter in one equation by using the second equation. Recall that we have that x=t. Then, by replacing in the second equation, we have the following
