Find the slope of the line passing through (1,3) and (-2,5)
Alenkasestr [34]

Hi there! :)

Step-by-step explanation:

Slope=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}

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

<u><em>Slope is -2/3</em></u>

<u><em>Final answer is -2/3</em></u>

Hope this helps!

Thanks!

-Charlie

Have a nice day! :)

erastova [34]

Answer:

Step-by-step explanation:

Let x represent the number of spelling questions in the test.

Let y represent the number of vocabulary questions in the test.

Mrs morals wrote a test with 15 questions covering spelling and vocabulary. This means that

x + y = 15

Spelling questions (x) are worth 5 points and vocabulary questions (y) are worth 10 points. The maximum number of points possible on the test is 100. This means that

5x + 10y = 100 - - - - - - - - - - - 1

Substituting x = 15 - y into equation 1, it becomes

5(15 - y) + 10y = 100

75 - 5y + 10y = 100

- 5y + 10y = 100 - 75

5y = 25

y = 25/5 = 5

x = 15 - y = 15 - 5 = 10

A line has a slope of 1/2 and passes through the point (6,2).
Mamont248 [21]

Answer:

a) y-2=1/2(x-6) b) The y-intercept of this line is -1.

Step-by-step explanation:

y-y1=m(x-x1)

y-2=1/2(x-6)

------------------

y=1/2x-6/2+2

y=1/2x-3+2

y=1/2x-1

y=mx+b where m=slope and b=y-intercept.
