Answer:

Slope: \frac{3}{5}

Y-intercept: -3

Equation: y=\frac{3}{5} x-3

Graph is attached.

Step-by-step explanation:

To find your slope using two points, use the slope formula.

\frac{y2-y1}{x2-x1} \\

Your y1 is -6, your y2 is 3.

Your x1 is -5, your x2 is 10.

\frac{3-(-6)}{10-(-5)} \\\\\frac{9}{15} \\\\\frac{3}{5} \\

Now that you have your slope, use it and one of your points in point-slope form to find your y-intercept.

y-y1=m(x-x1)\\y-3=\frac{3}{5} (x-10)\\y-3=\frac{3}{5} x-6\\y=\frac{3}{5} x-3

Answer:

A. In the graph,

Go 5 units left side from the origin in the x-axis then from that point go downward 6 unit, we will get (-5, -6),

Now, go 10 unit right from the origin in the x-axis then from that point go upward 3 unit, we will get (10, 3),

B. The slope of the line passes through (-5, -6) and (10, 3),

m=\frac{3-(-6)}{10-(-5)}=\frac{3+6}{10+5}=\frac{9}{15}=\frac{3}{5}

C. Since, the equation of a line passes through (x_1, y_1) with slope m is,

y-y_1=m(x-x_1)

Thus, the equation of the line is,

y+6=\frac{3}{5}(x+5)----(1)

For y-intercept,

x = 0,

y+6 = \frac{3}{5}(0+5)\implies y = 3-6=-3

That is, y-intercept is -3.

D. From equation (1),

5y + 30 = 3x + 15

\implies 3x - 5y = 15

Which is the required linear function.

What is the value of x in the equation -6x = 5x+ 22?<br> -22<br> 0 -2<br> 02<br> O 22
Ivahew [28]

Answer:

x = -2

Step-by-step explanation:

Solve  -6x = 5x + 22

add 6x to both sides

0 = 6x + 5x + 22

0 = 11x + 22

11x = -22

x = -22/11

x = -2

Jada asked some students at her school how many hours they spent watching television last week, to the nearest hour. Here are a
-Dominant- [34]

Answer:

100

Step-by-step explanation:

Based on the histogram given :

The vertical axis gives the number of student in the school :

For the range :

0 - 5 = 40

5 - 10 = 30

10 - 15 = 20

15 - 20 = 5

20 - 25 = 3

25 - 30 = 2

Taking the sum :

(40 + 30 + 20 + 5 + 3 + 2) = 100

MA_775_DIABLO [31]

Step-by-step explanation:

let's assume one month is 30 days you would multiply 10 by 30.

10 \times 30 = 300

which would be 300 hours in 1 month

now if one month is 31 days you would simply multiply 10 by 31.

10 \times 31 = 310

which would be 310 hours
