6 0
2×+y=0,
×-y=6

Add the 1st to the 2nd equation==> 3x +y-y=6+0==> 3x=6 & x=2

Plug 2 into any of the equation & you will get y=-4

Please help!!!!!!!!!!!!!!!!!
Andrej [43]

Answer:

y = 2/3x + 4

Step-by-step explanation:

Slope-intercept form of a line:

  • y = mx + b
  • where m = slope and b = y-intercept

To find the equation of a line, we need two points that the line passes through.  

We can use the x-intercept and y-intercept of the line: (-6,0) and (0,4), respectively.

Find the slope of the line using these two points:

  • Slope formula: \displaystyle \bf  \frac{y_2-y_1}{x_2-x_1}

Plug the two points into the formula.

  • \displaystyle \frac{4-0}{0-(-6)}

Subtract and simplify this fraction.

  • \displaystyle \frac{4}{6} =\frac{2}{3}

The slope of this line is m = 2/3.

Now we can look at the graph to determine the y-intercept of this line; the line intersects the y-axis at (0,4) so the constant b = 4.

We can use the slope, m, and the y-intercept, b, and substitute these values into the slope-intercept form of a line.

  • y = 2/3x + 4

The equation of the line is y = 2/3x + 4.

Complete the function table and write the rule.

Input  Output
32       20
14        2
?         -6
-2          -14
-10       ?
OK,  With the ones I have gotten full answers on,  the pattern is y=x-12
So,  ? one is 6 because you ADD 12.
? 2 on the y side is -22 because you subtract 12!
