Question 163858
y = 2x-4 Plot the y-intercept and find other points using the slope. Connect the points.

Select different values for x and simplify.

Let x = -1, 0, and 1 and simplify.  You can pick any number for x and simplify but I always choose simple numbers.

Let x = -1

y = 2(-1) - 4

y = -2 - 4

y = -6

Our first point is (-1, -6).

===========================

Let x = 0

y = 2(0) - 4

y = 0 - 4

y = -4

Our second point is (0, -4).

============================

Let x = 1

y = 2(1) - 4

y = 2 - 4

y = -2

Our third point is (1, -2).

Now, get some graph paper and plot the 3 points I just found.

After plotting each point, connect the points with a straight line.
