Hello from MrBillDoesMath!

Answer: y = -2

Discussion. Using y= mx +b with m = 0, gives

y = b

But what is "b"? The line passes through the point (4,-2) so y = -2. Hence

y = -2

Thank you,

which pair of these points defines a line with a slope 2/3? A. (2, 6) and (3, 0) B. (6, 2) and 3, 0) C. (6, 2) and (0, 0) D. (2,

Answer:

B. (6,2) and (3,0)

Step-by-step explanation:

To find the slope the equation is $\frac{y_{2-y_{1} } }{x_{2} -x_{1} }$ so for (6,2) and (3,0) the equation would look like this $\frac{0-2}{3-6}$ which simplies down to $\frac{-2}{-3}$ and a negative divided by a negative is a positive so you're slope is $\frac{2}{3}$ and it matches the question.
