Equation is y = 15/17 x - 42/17

Step-by-step explanation:

Step 1:

Find slope of the line. m = (y2 - y1)/(x2 - x1) Here, x1 = 13, x2 = 30, y1 = 9, y2 = 26

⇒ m = (26 - 9)/(30 - 13) = 15/17

Step 2:

Form the equation with slope m=15/17

⇒ y = 15/17 x + b ------ (1)

Step 3:

Find the y-intercept, b. Substitute the values of x = 13 and y = 9 in the eq(1) to find b.

⇒ 9 = 15/17 × 13 + b = 195/17 + b

⇒ b = 9 - 195/17 = 153 - 195/17 = -42/17

Step 4:

Substitute the values of m and b to form the equation

⇒ y = 15/17 x - 42/17

Mr. Howard is a student teacher at the local junior high. His first‐period class of 40 students averaged 96% on a recent test. H

kodGreya [7K]

Answer:

The combined average is 94%

Step-by-step explanation:

for first period, number of students =40

average =96%

for second period, no of students =20

average =90%

but $average = \frac{sum of scores}{no of students}$

let $S_1$ =sum of students for the first period

$S_2$ =sum of students for the second period

for first period;

$\frac{S_{1} }{40} =96%$

$S_{1}= 96*40=3840$

for second period,

$\frac{S_{2} }{20} =90%$

$S_{1}= 90*20=1800$

therefore the combined average = $\frac{S_1+S_2}{40+20}$

that is $\frac{3840+1800}{40+20}$ $= 94%$

so combined average is 94%
