I think it does equal x but not really fully sure

How to solve Y=1/2X+2

Oxana [17]

<span>x-intercept is when y = 0

0 = -1/2x - 2
1/2x = -2
x = -4
x-intercept = (-4,0)

y-intercept is when x = 0

y = -1/2(0) - 2
y = -2
y-intercept = (0, -2)
(note that in the form y = mx+b, b is the y-intercept, so in y = -1/2x - 2, -2 is the y-intercept)

Now to graph, simply plot these two points (-4, 0) and (0, -2) and draw a line between them.

First, we must find the common denominator (12) ✵

10/12-6/12 ✵ ✵ ✵ ✵

Now, why 10? ✵ ✵ ✵

Because we CAN'T just take the denominator and change it; we must change both the denominator AND the numerator:

✵ • - ○

4/12 ✧ ✩ ✶ ✺ ✱

We can simplify, or reduce, this fraction: ✱ ✱
