2x + 4y = 12..subtract 2x from both sides
4y = -2x + 12...divide both sides by 4
y = -2/4x + 12/4....reduce
y = -1/2x + 3 <===

Ok, when solving for this types of equation, i have learned a good trick. We are solving for y, so just put your finger in front of x to take it out and solve from there. With that, we are left with 4y=12. Divide both sides by 4 and get your answer. y=3.
Hope this helps

How would you do 1/2 to 1/4

Paraphin [41]

1/2 to 1/4

You can read fractions a few different ways:

1/2 = 50% or .50

1/4 = 25% or .25

If you divide 50 (1/2) by 2, you get 25 (1/4)

So to find 1/4 of 1/2, you would divide, and in this case by 2.

Hope that helped!

Write an equation of a line with the given slope and y intercept from the graph

goblinko [34]

Answer:

y = 1.5x - 1 or y = 1 1/2x - 1 or y = 3/2x - 1

Step-by-step explanation:

y = mx + b

b is the point on the y

y = -1

b = -1

now the slope
