Graph this equation:
When we have an equation in standard form, we can graph it by finding the intercepts and then drawing a line between them.
To find the x-intercept, let y = 0. Plug it in and solve.
2x = -3
We'll do the same thing for the y-intercept, except with x = 0.
y = -6
We have intercepts of (-1.5, 0) and (0, -6). Plot and draw, people!
We're going on a treasure hunt. And by "treasure" we mean "intercept." Which is basically the opposite of treasure. Now we're sad.
The x-intercept, where y = 0, is:
x = -4
The y-intercept is where x marks the spot, with x = 0.
-y = 2
y = -2
We have intercepts of (-4, 0) and (0, -2). Mark them on the treasure map. And by "treasure map" we mean "coordinate plane." Again, kinda misleading.
x + 4y = 4
Intercepts, plotting, problem done. Go.
Let's plug in y = 0 to find the x-intercept.
x + 4(0) = 4
x = 4
This makes the x-intercept the point (4, 0).
Next up is x = 0, netting us the y-intercept.
3(0) + 4y = 4
4y = 4
y = 1
A y-intercept of (0, 1). We can work with this.
Problem done. Now let's go sledding down this line.
