On the first question, the formula would be m=\frac{y2-y1}{x2-x1} and the value we got is -4/3, so D.
On the second quesiton, the slope in the given equation of the line is -2, its negative reciprocal is 1/2, so A.
On the third question, use the slope formula above and the value you would get is zero, so A.
On the fourth question, the equation of the line perpendicular to line QR is y=2x+b, to find b, just substitute the point (5,6) to the equation. That would make b = -4. the final equation of the line would be: y=2x-4, so D.
On the fifth question, the equation of the line parallel to line QR is y = -2x + b. substitute the point (4,5) to the equation, and you'll get b = 13. the final equation of the line would be y=-2x+13, so A.
Answer:
The answer is
![2x - 6 = 4](https://tex.z-dn.net/?f=2x%20-%206%20%3D%204)
Step-by-step explanation:

Answer:
A and D are the true number sentences
61 would be the most simplified without expressions
Answer:
the answer is b.
Step-by-step explanation:
8 less indicates that 8 is being subtracted from a number.
the product of six and a number means multiplication so (6)(x).
with these statements, 8 would have to be subtracted from six times x
