The line shown represents the amount of money left on a gift card, y, after Mina buys lattes. After buying 2 lattes, she has $2 left. What is an equation of the line in point- slope form?

Step-by-step explanation:

Given that after she buys 2 lattes, she has $2 left, this represents a point on the line in the graph, which is (2, 2).

Point-slope form of equation for a line is given as . Where,

(a, b) = a point on the line

m = slope

The equation of the line in point-slope form is given by the formula, , where,

(a, b) = coordinates of a point on the line.

We already have values for (a, b) = (2, 2), let's find the slope (m).

Using (2, 2) and any point on the line, such as (0, 8), we can find the slope as follows:

Now we know that a = 2, b = 2 , and m = -3. Let's plug in this values into the point-slope equation as shown below:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
