Final answer:
To find the x-intercept of the linear equation y = 2x + 4, set y to 0 and solve for x, resulting in the point (-2, 0), which is choice B.
Step-by-step explanation:
The x-intercept of a graph is the point where the graph crosses the x-axis. For the linear equation y = 2x + 4, the x-intercept can be found by setting y to zero and solving for x. Setting y to zero gives us the equation 0 = 2x + 4. To find the value of x, we subtract 4 from both sides of the equation to get -4 = 2x. Then we divide both sides by 2 to find x = -2. Therefore, the x-intercept of the graph is the point (-2, 0), which corresponds to answer choice B.
