Answer:

A is correct

Step-by-step explanation:

A has no solution because since the slopes are the same, setting both equations equal to each other will cancel out the slopes and result in 8=16, meaning no solution will make both sides equal to each other.

B does have a solution because of different slopes

C does have a solution because of different slopes

D does have a solution because of different slopes

What is the slope, m, and the y-intercept of the line that is graphed below?

Pepsi [2]

Answer:

Slope: 1

Y-intercept: (0,3)

Step-by-step explanation:

The y intercept is when the slope reaches the y-axis line. In this case, it is given to us. Anything that is formed like this: (0, y) is the y-intercept.

Y intercept: (0, 3)

For slope, you can use the formula rise over run. $\frac{Rise}{Run}$

From the picture, I have drawn the rise over run, which is $\frac{3}{3}$ , which is also 1.

Slope: 1

Answer:

Do not worry about the decimal point until you get your answer.

Just multiply like there is no decimal at all.

When you do get your answer, count how many decimal places are after the decimal point. In this case, we have two decimal places.

3.9

7.1
