Answer:

y = \frac{1}{3}x - 5

Step-by-step explanation:

Given

slope\ (m) = \frac{1}{3}

y\ intercept = -5

Required

Determine the line equation in slope intercept

The equation of a line in slope intercept is:

y = mx + b

Where

m = slope = \frac{1}{3}

b = y\ intercept = -5

So, y = mx + b becomes

y = \frac{1}{3}x - 5

Rina draws a plan of her school on a coordinate grid. She plots the school gate at point p(-8,-1) and the library at point Q(2,5
natka813 [3]

Answer:

The coordinates of the science lab is:

x = -14/3  ,  y = 1

Step-by-step explanation:

∵ P is (-8 , -1) and Q is (2 , 5)

∵ The point of the science lab is (x , y)

∵ The science lab point divided PQ at ratio 2 : 1 from Q (two thirds PQ)

∴ x=\frac{m_{1}x_{p}+m_{2}x_{q}}{m_{1}+m_{2}}

∴ y=\frac{m_{1}y_{p}+m_{2}y_{q}}{m_{1}+m_{2}}

∴ x=\frac{2(-8)+1(2)}{1+2}=\frac{-14}{3}

∴ y=\frac{2(-1)+1(5)}{2+1}=\frac{3}{3}=1

∴ The point of science lab = (-14/3 , 1)

Please answer number 12. Very urgent!! 18 points!
Ksenya-84 [330]

Answer:

10 5/12

When the numerator is larger than the denominator, we take  groups of whole fractions  (The numerator and denominator are equal) and add 1 to the whole number for each group. Whatever remains when we no longer have the numerator larger than the denominator is left as a fraction.

Step-by-step explanation:

6 3/4 + 3  2/3

We need to get a common denominator

The common denominator is 12

We need to rename the fractional parts  to out of 12

6 3/4 = 6 3/4*3/3 = 6 9/12

3 2/3 = 3 2/3*4/4 = 3 8/12

6 9/12+ 3 8/12

9 17/12

But the numerator is larger than the denominator

We take 12/12 from the fraction  and add it to the whole number

9 17/12-12/12  +1

9+1 5/12

10 5/12
