Question

I am confused about this question ​

Answer 1

Answer:

X = 5

Step-by-step explanation:

When the line is going vertically down, the x-intercept is always the equation of the line.

Answer 2

Linear Equations of Vertical Lines

Linear equations are typically organized in slope-intercept form:

$y=mx+b$

• m = slope
• b = y-intercept (the value of y when the line passes through the y-axis)

However, for vertical line equations, we write them a little differently:

$x=d$

• d = the x-intercept (the value of x when the line passes through the x-axis)

We write equations for vertical lines like this because they might not always have a y-intercept.

Solving the Question

We're given:

• Line L passes through the x-axis when x = 5

This means that the x-intercept of the line is 5. Plug this into $x=d$:

$x=d$

$x=5$

Answer

$x=5$
