Just so u know, when u have just the variable (w), it is the same as 1w...although the " 1 " is not written, just understood to be there.

2w + w + 2w + w = 42...combine like terms
6w = 42...now divide both sides by 6
(6/6)w = 42/6
1w (or just w) = 7

First you combine the like terms which are the Ws.
And if there's no number in front of the variable (w in this case) it

Please help! Find the equation of the line and I will mark as brainliest IF answer is right. &lt;3
Hoochie [10]
<h3>Answer:  y = (3/4)x + 13/4</h3>

This is the same as writing y = 0.75x + 3.25

slope is 3/4 = 0.75

y intercept is 13/4 = 3.25

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

Explanation:

One marked point on this line is (-3,1)

Another point is at (1,4)

Let's find the slope of the line through these two points.

m = (y2-y1)/(x2-x1)

m = (4-1)/(1-(-3))

m = (4-1)/(1+3)

m = 3/4

m = 0.75

Now let's use point slope form to find the equation of the line

y - y1 = m(x - x1)

y - 1 = 0.75(x - (-3))

y - 1 = 0.75(x + 3)

y - 1 = 0.75x + 2.25

y = 0.75x + 2.25 + 1

y = 0.75x + 3.25

If you wanted, you can convert those decimal values to fraction form

  • 0.75 = 75/100 = 3/4
  • 3.25 = 325/100 = 13/4

That means the equation

y = 0.75x + 3.25

is the same as

y = (3/4)x + 13/4
