Ayogurt with 1 topping is sold for $3.65. additional toppings can be added for $0.45 cents each. if y represents the total cost and x represents the total number of toppings added, which function rule describes this pattern? a. y=0.45x+3.65 b. y=3.65+0.45(x-1) c. y=3.65+0.45(x+1) d.3.65(x-1)+0.45

since the 3.65 price includes 1 topping when you calculate the cost of the additional toppings it would be x-1

 so the equation would be y=3.65 +0.45(x-1)

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
