1. Find the equations of the following lines. a. The line that passes through points A(-1,1) and B(3,0).​

Step-by-step explanation:

First, find the slope. The slope can be found by using the following equation:

slope

Let:

Plug in the corresponding numbers to the corresponding variables:

Plug in into the equation for slope:

y = mx + b

Note that:

y = y

m = slope

x = x

b = y-intercept

Plug in a point into the equation. In this case, I will use b(3 , 0). Remember (x , y):

Equation:

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

depends on how many days you are talking about
