The graph is y=1.4x please help!!

kiruha [24]

The true statements about the equation y = 1.4x are

(a) The equation represents a proportional relationship
(b) The unit rate of y with respects to x is 1.4
(d) A change of 2 units in x results in a change of 2.8 units in y

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

<h3>How to determine the true statements?</h3>

The equation is given as:

y = 1.4x

The above equation is a proportional linear equation.

This is so because proportional linear equations are represented as;

y = mx

Where m represents the unit rate of change

So, we have:

m = 1.4

Rewrite as:

m = 14/10

Simplify

m = 7/5

When x = 2, we have:

y = 1.4 * 2

Evaluate

y = 2.8

Hence, the true statements about the equation y = 1.4x are (a), (b) and (d)

5.Find the slope of a line perpendicular to

Lemur [1.5K]

Hi there!

When the slopes of two perpendicular lines are multiplied the outcome will be -1.

The slope is the number that is positioned in front of the variable x in the formula. In this case the slope of the given line is -2/5.

Let's call the slope of the perpendicular line m and take into account the given data of the question and my earlier explanation. We then find the following:

$- \frac{2}{5} \times m = - 1$
Divide both sides by - 2/5.

$m = \frac{ - 1}{ - \frac{2}{5} } = 2 \frac{1}{2} = \frac{5}{2}$
The answer is B.

~ Hope this helps you!
