The graph provided represents the line given by the equation $y = x - 2$. To solve part 4a, we need to determine the x-intercept, where the line crosses the x-axis.

To find the x-intercept:

1. Set $y = 0$ because the y-value at the x-intercept is always zero.
2. Solve for $x$.

Step-by-Step Solution:

Starting with the equation: $y = x - 2$ Set $y = 0$: $0 = x - 2$ Solve for $x$: $x = 2$

Thus, the coordinates of the x-intercept are $(2, 0)$.

Here are 5 related questions for practice:

1. What is the y-intercept of the line $y = x - 2$?
2. How would the graph change if the equation were $y = x + 3$?
3. Find the slope of the line $y = x - 2$ and explain its significance.
4. How do you find the point where two lines intersect?
5. What is the distance between the origin and the x-intercept of $y = x - 2$?

Tip: The slope-intercept form of a line is $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept.
