Answer

Find out the slope intercept form .

To prove

The slope intercept form is y = mx + b

where m is the slope and b is the y-intercept

As given

$Slope = \frac{-7}{2}$

y intercept = 4

Put all the values in the slope intercept form

$y = \frac{-7x}{2} + 4$

Therefore the slope intercept form is

$y = \frac{-7x}{2} + 4$

ANSWER:

The 75% of 400 is 300.

SOLUTION:

Given, 75% of 400.

We have to Write and evaluate an expression to find the answer. Then we have explain how to use the model to justify the answer.

Now, let x and y be any two numbers such that, 0 ≤ y ≤ 100

$\text { Then, } y \% \text { of } x \text { will be equal to } \frac{y}{100} \times x$

Now, let us substitute the given values in above expression.

$x=400 \text { and } y=75 \rightarrow \frac{75}{100} \times 400=75 \times 4=300$

We have to do the same procedure for any given values.

Hence, the 75% of 400 is 300.
