What is a correct equation for the line passing through the point (-2,1) and having slope m=1/2

Step-by-step explanation:

The point-slope form of an equation of a line:

m - slope

We ahve the slope m = 1/2 and the point (-2, 1). Substitute:

- point-slope form

Covert to the slope-intercept form (y = mx + b):

         use the distributive property

         add 1 to both sides

  - slope-intercept form

Convert to the standard form (Ax + By = C):

    multiply both sides by 2

       subtract x from both sides

        change the signs

  -  standard form

Convert to the general form (Ax+By+C=0):

       add 4 to both sides

  - general 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.

answer is c
