Answer:
y - 7 = -2(x - 4)
Step-by-step explanation:
We are asked to write the equation of a line in point slope form
Step 1 : find slope
We are given the slope to be -2
Slope m = -2
Step 2: substitute m into point slope form
y - y_1 = m( x - x_1)
y - y_1 = -2 ( x - x _1)
Step 3: substitute the point into the equation
y - y_1 = -2( x - x _1)
( 4 , 7)
x_1 = 4
y_1 = 7
y - 7 = -2( x - 4)
We don't need to open the bracket because we are asked to write the equation in a point slope form
To distribute through parenthesis, u take the number outside of the parenthesis and multiply by everything inside the parenthesis.
6(x + 3) = (6 * x) + (6 * 3) = 6x + 18 <==
In the given question, there are several information's of immense importance. using these given information's the required answer can be easily deduced. It has already been given that Tom has a total amount of $240. He bought 22 boxes of drinks at $4 per box. rest he spent on buying the 8 boxes of sandwiches.
A. The amount of money the drinks cost in total = (22 * 4) dollars
= 88 dollars
So Tom spent $88 on the drinks
B. Now we have to first find the amount spent by Tom on the box of sandwiches.
Total amount spent by Tom on sandwiches = (240 - 88) dollars
= 152 dollars
Then the amount of money spent by Tom for buying 1 box of sandwich = (152/8) dollars
= 19 dollars
So Tom had to pay $19 for buying a single box of sandwich.
