If two points on line l above have coordinates (0, A) and (2, −3), and the slope of the line is A, then what is the value of A?
Vlada [557]

Answer:

A = -1

So, option (B) is the correct answer.

Step-by-step explanation:

The two points on line have coordinates: p (x₁, y₁) = (0, A) and q(x₂, y₂) = (2 , -3)

Slope of line = A

Slope of line = \frac{y_{2} - y_{1}}{x_{2} -x_{1}}

Now since the slope of line is A  and its has two coordinates (0, A) and (2 , -3), ∴

A = \frac{y_{2} - y_{1}}{x_{2} -x_{1}}

A = \frac{-3 - A}{2 - 0}

2A = -3 - A

2A + A = -3

3A = -3

A = -1

So, option (B) is the correct answer.

SSSSS [86.1K]

Answer:

There will be 7 students on each bus.

Step-by-step explanation:

If the class of 63 students is divided into 9 buses with the same number of students traveling in each one, to determine the number of students traveling in each bus it is necessary to perform the following mathematical calculation:

63/9 = X

7 = X

Thus, in each bus 7 students will travel, and in this way all buses will carry the same number of students.

almond37 [142]
<span>The ordinate is three more than twice the abscissa
</span>Ordnate: y; Abscissa: x
y=3+2x

x=-1→y=3+2(-1)=3-2→y=1→(x,y)=(-1,1)
x=0→y=3+2(0)=3+0→y=3→(x,y)=(0,3)
x=-1/3→y=3+2(-1/3)=3-2/3=(3*3-2)/3=(9-2)/3→y=7/3→(x,y)=(-1/3,7/3)

Answer: Option <span>A) {(-1,1),(0,3),(-1/3,7/3)}</span>
