If h(x) = −2x − 10, find h(−4). −2 −18 −3 −16

Anuta_ua [19.1K]

If h(x) = -2x - 10 you should put the -4, -2. -18, -3 or/and -16 in the place of the x in the formula.
So for example:

h(-4) = -2 * (-4) - 10 = 8 - 10 = -2

Or at least, that's what I think the answer should be.

Good luck!

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,

ipn [44]

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.
