Answer:

option a

Step-by-step explanation:

m = slope

m=y2-y1/x2-x1

first point (14,1)

second point (18,17)

so we have:

m=(17-1)/(18-14)

she did not keep the order of the point

Answer:

A. She did not keep the order of the points the same in the numerator and denominator.

The slope is 4.

Step-by-step explanation:

To solve this problem, first you have to use the slope formula of \displaystyle \frac{y_2-y_1}{x_2-x_1}=\frac{rise}{run}.

\displaystyle y_2=17\\\\\displaystyle y_1=1\\\\\displaystyle x_2=18\\\\\displaystyle x_1=14\\

Solve.

\displaystyle \frac{17-1}{18-14}=\frac{16}{4}=4

Therefore, the slope is 4, and she did not keep the order of the points the same in the numerator and denominator.

Solve the system of equations by substitution. What is the solution for x? 2x + y = 1 4x + 2y = −1
lapo4ka [179]
Solve your system of equations.

2x+y=1;4x+2y=−1

Solve 2x+y=1 for y:

2x+y+−2x=1+−2x(Add -2x to both sides)

y=−2x+1

Substitute (−2x+1) for y in 4x+2y=−1:

4x+2y=−1

4x+2(−2x+1)=−1

2=−1(Simplify both sides of the equation)

2+−2=−1+−2(Add -2 to both sides)

0=−3

Answer: No solution. C)

(2x + 3y) + (4x - 3y) = 11+(-5)
Maurinko [17]

Answer:

The correct option should have been 6x=6.

Step-by-step explanation:

Given the expression

\left(2x\:+\:3y\right)\:+\:\left(4x\:-\:3y\right)\:=\:11+\left(-5\right)

solving the expression

\left(2x\:+\:3y\right)\:+\:\left(4x\:-\:3y\right)\:=\:11+\left(-5\right)

Remove parentheses:  (a) = a

2x+3y+4x-3y=11-5

Group like terms

3y-3y+2x+4x=11-5

Add similar elements

6x=6

It is clear that not a single given option is 6x=6. It means no option is correct. It seems you mistyped the correct options.

The correct option should have been 6x=6.
