Find the equation of line passing through points A (1, 3) and B (3, 7).

Sidana [21]

Solution:

To find the equation of line passing through points A (1, 3) and B (3, 7).

we know that, to derive the equation of a line we first need to calculate the slope of the line. Slope m of a line at points $(x_{1} ,y_{1})$ and $(x_{2}, y_{2})$ is given by - $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ .

Slope of the line at point A(1,3) and B(3,7)

$m=\frac{7-3}{3-1}$ .

$m=\frac{4}{2}$ .

$m=2$ .

Equation of a line using a point and a slope , $y-y_{1}= m(x-x_1)$

$y-3= 2(x-1)$

$y-3= 2x-2$

$y= 2x-2+3$

$y= 2x+1$

The equation of line passing through points A (1, 3) and B (3, 7) : $y= 2x+1$

-3.5 x 0.2 =??? ;w;<br><br><br> A. -0.7<br> B. 0.7<br> C. -3.3<br> D. -0.7

Dafna11 [192]

Answer:

A and D

Step-by-step explanation:

It can't be B because of the negative...

It would have to be less than 3.3 since 0.2 is less than and the 3.3 is negative

A and D are the same?

-3.3 * 0.2 = -0.7

Sarita showed the steps to solving the equation.

shtirl [24]

The option that explains Sarita's mistake is Sarita’s solution is correct. She made an error in her verification.

<h3>What was Sarita's mistake?</h3>

The given equation is: 5(x - 3) + 7(x + 4) = 73

In order to determine the value of x, take the following steps:

1. Apply the Distributive property:

5x - 15 + 7x + 28 = 73

2. Add similar terms together:

12x + 13 = 73

3. Combine similar terms:

12x = 73 - 13

4. Add similar terms

12x = 60

5. Divide both sides of the equation by 12

x = 60 / 12

x = 5

In order to verify the answer, substitute for x in the given equation :

5(5 - 3) + 7(5 + 4) = 73

5(2) + 7(9) = 73

10 + 63 = 73

73 = 73

Jessica reads a story about a turtle that swam 16 feet in 24 seconds. She assumes that the time, t, that it takes the turtle to

Monica [59]

You would start by figuring out the distance the turtle swims every second by dividing 24 by 16.
24➗16=1.5
From this we can take the numbers from either T: 1, ___, 24, 45 or D: ___, 10, 16, ___ to figure out the blank spaces for the other using multiplication or division. Divide T by 1.5, or multiply D by 1.5 to find the other

T: 1, 15, 24, 45
D: 1.5, 10, 16, 30
