Write an equation in point-slope form of the line that passes through the given points:

1. (4, 1), (-2, 7)

2. (1, 3), (-3, 0)

3. (-2, -5), (4, -1)

-Use Slope formula first, to find the slope and after you have the slope, use the slope and the first point or coordinate for the point-slope formula:

Slope Formula:

 ( where the first point is and the second point

Point-slope form:

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.

(-1,-0.5)
