Question

1. graph the linear function: $y = 2x - 4$

instructions

• click the graph tab.
• click on the graph background to add a point. add two points to create a graph. drag a point or type in x and y coordinates to edit its position. click on a point to delete it.

graph 1

Explanation:

Step1: Find y-intercept (x=0)

Substitute $x=0$ into $y=2x-4$:
$y=2(0)-4=-4$
Point: $(0, -4)$

Step2: Find x-intercept (y=0)

Set $y=0$, solve for $x$:
$0=2x-4$
$2x=4$
$x=2$
Point: $(2, 0)$

Step3: Plot and connect points

Mark $(0, -4)$ and $(2, 0)$ on the grid, then draw a straight line through them extending beyond both points.

Answer:

Graph the line passing through the points $(0, -4)$ and $(2, 0)$.
