Answer:
You negate the y-coordinate.
Step-by-step explanation:
A reflection about the x-axis will not change the x-coordinate of any point. This is because it goes straight across the x-axis; this does not change how much left or right of the origin the point is.
However, since each point is reflected across the x-axis, the y-coordinate will change. If it was above the x-axis, it will be below; if it was below the x-axis, it will be above. It will still be the same number of units away from the x-axis, however. This has the effect of negating the y-coordinate.
Slope is the rise/run of the line. With the rise being how far apart the two points are on the y axis, and the run being how far apart the two points are on the x axis.
In this case, the first point is 6 units down from the other and 4 units over from it. (6/4) then from there you would simplify your fraction. (Both numerator and denominator can be divided by 2).
Your slope in total is 3/2. Hope this helped.
Answer:
-17x+31
Step-by-step explanation:
-3(3<em>x-5</em><em>)</em><em>-4</em><em>(</em><em>2x-4</em><em>)</em>
<em>=</em><em> </em><em>-9x</em><em>+</em><em>1</em><em>5</em><em>-8x</em><em>+</em><em>1</em><em>6</em>
<em>=</em><em> </em><em>-17x</em><em>+</em><em>3</em><em>1</em>
