$45.75 because you take the 2.75 and times it by how may books which is 13 and you get $35.75 then you add your $10 and it will give you $45.75

2.75b+10 (write the equation)
2.75(13)+10 (substitute for b)
35.75+10 (multiply)
45.75

Given:

The inequality is:

y>5x+3

To find:

The y-intercept, slope and type of line (solid or dotted).

Solution:

The slope intercept form of a line is:

y=mx+b            ...(i)

Where, m is the slope and b is the y-intercept.

We have,

y>5x+3

The relation equation is:

y=5x+3             ...(ii)

On comparing (i) and (ii), we get

m=5

b=3

It means the slope is 5 and the y-intercept is 3.

The sign of the inequality in the given inequality is ">". It means the boundary line is not included in the solution set. So, the boundary line is a dotted line.

Therefore, the slope is 5, the y-intercept is 3 and the line is a dotted line.

In the equation y = -2x, if x is doubled, what happens to y? stays the same doubles quadruples unknown, since a value for x is n
OLEGan [10]
In an equation like that, y would double into 2y. But just keep in mind that what happens to one side must happen to another.
