Question

Graph the given equation by evaluating integer values of x from -2 to 2 and plotting the resulting points.
y = -2x - 4

Answer 1

Graphs are created from functions and equations.

See attachment for the graph of $\mathbf{y = -2x - 4}$

The equation is given as:

$\mathbf{y = -2x - 4}$

When x = -2, we have:

$\mathbf{y = -2(-2) - 4 = 0}$

When x = -1, we have:

$\mathbf{y = -2(-1) - 4 = -2}$

When x = 0, we have:

$\mathbf{y = -2(0) - 4 = -4}$

When x = 1, we have:

$\mathbf{y = -2(1) - 4 = -6}$

When x = 2, we have:

$\mathbf{y = -2(2) - 4 = -8}$

So, the points on the graph are:

$\mathbf{(x,y) = (-2,0)(-1,-2)(0,-4)(1,-6)(2,-8)}$
