Write the equation in standard form of the line that passes through the points (7,-3) and (-3,1).

y-intercept form of that equation:

y=-2/5x+b

1=-2/5(-3)+b

1=6/5+b

b=-1/5

y=-2/5x-1/5

standard form:

2/5x+y=-1/5

srry im too busy rn so i couldnt explain very well :/

Step-by-step explanation:

Standard Form: 4/10x + y = -0.2

Step-by-step explanation:

(7,-3) and (-3,1)

m = y2 - y1/x2 - x1

m = 1 - (-3)/-3 - 7

m = 1 + 3/-10

m = -4/10

y - y1 = m(x - x1)

y - 1 = -4/10(x + 3)

y - 1 = -4/10x - 1.2

y = -4/10x - 1.2 + 1

y = -4/10x - 0.2

Standard form: Ax + By = C

y = -4/10x - 0.2

4/10x + y = -0.2

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.
