Answer:

m = \frac{y_{2}-y_{1}  }{x_{2} - x_{1} } = \frac{0 - 4}{-3+2} = \frac{-4}{-1} = 4

4 is the slope

now we have to plug in the slope intercept formula where m is 4

you can find b by plugging one of the points

I choose (-3,0) since it is easier to work with

0 = 4(-3) + b

0 = -12 + b

12 = b

Our y intercept is 12

finally the slope intercept form is

y = 4x + 12

Slope formula - (y2 - y1)/ (x2-x1)

Slope intercept form = y = mx + b

Answer:

slope is 4 and y-intercept is 12

Step-by-step explanation:

To solve this problem, let's actually just write the equation of the line in slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.

Slope is change in y divided by change in x. Given (-3, 0) and (-2, 4), the slope will be: (4 - 0) / (-2 - (-3)) = 4 / 1 = 4. So, the slope is m = 4.

Now, our equation so far is y = 4x + b. To find b, plug in, say, -3 for x and 0 for y:

0 = 4 * (-3) + b

0 = -12 + b

b = 12

Then the slope is 4 and the y-intercept is 12.

X = 10

The triangles are similar by SAS, so we can set up a proportion of their sides.

9/(33-9) = 12/(3x+2)
9/24 = 12/3x+2

Reduce
3/8 = 12/3x+2

Cross multiply
3(3x+2) = 12*8

Distribute and multiply
9x + 6 = 96

Subtract 6
9x = 90

Divide by 9
x = 10

Check:
9/24 = 12/3x+2
9/24 = 12/3*10 + 2
9/24 = 12/30 + 2
9/24 = 12/32
3/8 = 3/8 :)

HELP!! Which of these linear equations best describes the given model?
viktelen [127]

Option B:

The linear equation that best describes the model is y = 40x + 800.

Solution:

Take two points which exactly on the line.

Let the points are (0, 800) and (10, 1200).

x_1=0, y_1=800, x_2=10, y_2=1200

Slope of the line:

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{1200-800}{10-0}

$m=\frac{400}{10}

m = 40

y-intercept of the line is where the line crosses at y-axis.

y-intercept (b) = 800

Equation of a line:

y = mx + b

y = 40x + 800

The linear equation that best describes the model is y = 40x + 800.

Option B is the correct answer.

Yakvenalex [24]
The 1st value is the time, and the 2nd value is the volume remaining in the can. the can is full at time x = 0 so y = 6.0 1 minute later x = 1 so y = 6.0 - 0.25 and for every 1 unit increase in x, y decreases by 0.25
