Answer:
14x-56y-42
Step-by-step explanation:
Given data
We have the expression
7(2x - 8y - 6)
Open the bracket we have
14x-56y-42
Hence the equivalent expression is
14x-56y-42
1 yard = 3 feet
Then the to find the number of feet in a number of yards use the conversion factor, 1 = 3 feet / yard
number of feet = number of yards * 3 feet/yard
If the number of feet is f and the number of yards is y, you can write the expression in this way:
f = 3y

An equivalent expression is 18a+9
Step-by-step explanation:
To find the equation of the line in slope intercept form, we must have the slope and the y intercept. Finding the slope is easy:
So now we want the y intercept. We can use either points to do this, so for simplicity let's use the second one since the numbers are smaller. First of all, we have:
y=-3x+b. Plugging in 6 for x and 2 for y we have, 2=-18+b which means b=20. Checking our answer we have:
y=-3x+20 which means 8=-3*4+20, which is true. So our equation is indeed y=-3x+20
