Answer:
y =
Step-by-step explanation:
From the given table,
Two points are (1, 15) and (7, 47)
If the two points and are lying on a line then slope 'm' of the line will be,
m =
=
=
=
Let the equation of a line passing through (h, k) is,
y - h = m(x - k)
If the line passes through (1, 15)
y - 1 =
y =
y =
y =
4(1/2x7)=12 <=> x28/2=12
x=12*2/28=24/28=12/14=6/7
The missing coordinate r is 11.
Solution:
Given points are (–15, 1) and (–7, r).
Slope (m) =
<u>To find the missing coordinate r:</u>
Slope formula:
Substitute the given values in the formula.
Do cross multiplication.
40 = 4r – 4
Add 4 on both side of the equation.
44 = 4r
Divide by 4 on both side of the equation.
11 = r
⇒ r = 11
Hence the missing coordinate r is 11.
Answer:
7 tables
Step-by-step explanation:
So if 6 students can fit at each table, you divide 38 by 6. You get 6 1/3 ,but since you can't get 1/3 of a table, you have to get 7
