What is the slope of the line represented by the equation y = x – 3?

2 answers:

5 0

The line is given in the form:
$y=mx+b$
Where $m$ is the slope and $b$ is the y-intercept.

Comparing the given line to the generic form we can see that $m=1$ , which is the slope.

You could also get this/check the answer by graphing the equation.

Hi there! The answer is "1".

The general formula of a line in slope-intercept form is y = mx + n. In this formula m (and therefore the number in front of the variable x) represents the slope of the line.

We have the following formula in the question: y = x – 3. To find its slope we must look at the number in front of the x (as I already mentioned). Since there is no visible number we must realise that the number in front of x is 1. Therefore, the slope of the line is 1.

Tell whether x and y show direct variation. x + y = 6

Over [174]

<h3>Answer: Not direct variation</h3>

The reason why is because it can't be written in the form y = kx

If we solved the given equation for y, we get y = -x+6. It has a y intercept of 6, but it should be zero if we wanted a direct variation equation.

Using a system of equations, it is found that Peter had $48 at first.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

Variable x: Peter's money.

Variable y: Henry's money.

The ratio of peters money to henrys money is 4 : 3, hence:

$\frac{x}{y} = \frac{4}{3}$

After Peter spent $12, they had the same amount, hence:

y = x - 12.

Then, replacing in the ratio:

$\frac{x}{y} = \frac{4}{3}$

$\frac{x}{x - 12} = \frac{4}{3}$

4(x - 12) = 3x

x = 48.

Answer:

Speed of boat in still water is 26km/hr

Step-by-step explanation:

Let the speed of boat in still water be x and speed of stream by y.

Speed at which it went upstream would be (x-y) and the speed at which it went downstream would be (x+y). According to question x+y=24 and x-y=28. x=26 and y=-2.
