Zielflug [23.3K]

Answer:

3rd option

Step-by-step explanation:

The equation of a line in point- slope form is

y - y₁ = m(x - x₁)

where m is the slope and (x₁, y₁ ) a point on the line

Here m = - 2 and (x₁, y₁ ) = 4. - 6 ) , then

y - (- 6) = - 2(x - 4) , that is

Leo needs to write an essay for history class. He estimates that he can write 1.5 pages per
alexandr1967 [171]
<h3>Answer:  y = 6-1.5x</h3>

========================================================

Work Shown:

x = number of hours

1.5x = number of pages written after x hours

y = 6-1.5x = number of pages left after x hours

--------------

In other words, if Leo can write at a pace of 1.5 pages per hour, and works for x hours, then he has written 1.5x pages so far. The difference of this with 6 will tell us what is left over. So the expression 6-1.5x is the amount of pages left, which is the value of y.

--------------

An example:

x = 2 so 1.5x = 1.5*2 = 3

At the 2 hour mark, Leo has written 3 pages. He has 6-1.5x = 6-1.5*2 = 6-3 = 3 pages left.
