Hey there! :)
Answer:
y -3 = -2(x + 4).
Step-by-step explanation:
Begin by calculating the slope of the line shown in the graph. Use the slope formula:
Plug in two coordinates:
Simplify:
Therefore, the slope of the line is 1/2.
A line that is perpendicular contains a slope that is the negative reciprocal. Therefore:
1/2 --> -2.
Plug the slope into the point-slope formula:
y -3 = -2(x + 4). This is your equation in point-slope form!
Answer:
The correct answer is B. b=3a + 2
Step-by-step explanation:
Plug in the values from column A into each equation and find which one works. In this case, the only option that works is B.
If the cup = S + 3
and the
saucer = S
then
(S + 3) + S = 12
2s + 3 = 12
2s = 9
s = 4.50
So by itself the saucer costs $4.50. To find the cost of the cup look to the beginning of the problem where we learned that
Cup = S + 3
cup = 4.50 + 3
cup = 7.50
So the saucer is $4.50 and the cup is $7.50...
4.50 + 7.50 = $12.00
It checks!
