First, figure out the slope of the line by solving for the slope between the two given coordinates.

Slope = y2 - y1 / x2 - x1

Substitute the coordinates.

Slope = 2 - (-4) / 2 - (-1)

Slope = 2 + 4 / 2 + 1

Slope = 6 / 3

Slope = 2

So, the slope of the equation here is 2.

Next, look for the y-intercept. You can find the y-intercept by looking on the graph. At what coordinate does the line intersect or cross the y-axis? By looking at the graph, you can see that the line intersects the y-axis at the coordinate point (0, -2). So, your y-interceot is -2.

Now, choose the equation that has a slope of 2 and a y-intercept of -2.

Remember that the standard form of any given linear equation should be in slope-intercept form.

y = mx + b

Substitute the slope and y-intercept

y = 2x - 2

By doing this, you can eliminate choices 1 and 4 because the equation should have 2x to represent the slope of 2.

The best choice is 2x - y = 2.

You have a slope of 2x and if the equation is put in standard form you would have a y-intercept of -2.

Solution: 2x - y = 2

Answer from: Quest

$\begin {array}{c|c}\underline {\quad x\quad}& \underline{\quad y\quad}\\ -2& 4\\-1& 2\\0& 0\\1& 2\\ 2& 4\\\end{array}$

step-by-step explanation:

y = | -2(-2) | → y = | 4 | → y = 4 ⇒ (-2, 4)

y = | -2(-1) | → y = | 2 | → y = 2 ⇒ (-1, 2)

y = | -2(0) | → y = | 0 | → y = 0 ⇒ (0, 0)

y = | -2(1) | c → y = | -2 | → y = 2 ⇒ (1, 2)

y = | -2(2) | → y = | - 4 | → y = 4 ⇒ (2, 4)
