1)  3x-7y=2
2)  If you're solving for x, you want to isolate it, so move the -7y to the right:
          3x = 7y + 2
3)  Now, to get x by itself, you divide both sides by 3
          3x/3 = (7y + 2)/3
4)  You get:
           x = 7/3y + 2/3

So, 3 * 4 = 12 , 7 * 1.5 = 10. 12-10 = 2 so x= 4<span /><span />

A direct variation function contains the points( -8,-6) and (12,9). Which equation represents the function ?
natulia [17]

Answer:

y = (3/4)x

Step-by-step explanation:

1)  Find the slope of the line.  As we go from ( -8,-6) to (12,9), x increases by 20 and y increases by 15.  Thus, the slope, m, is m = rise / run = 15/20 = 3/4

2) Recognize that the y-intercept is zero (0) because this is direct variation; the line goes thru the origin.

3) write the equation of the line:  y = mx + b becomes y = (3/4)x
