Find the slope and y-intercept for this table.

See below:

Step-by-step explanation:

To find the slope, we use the following formula:

For this case, we can use (6,60) as the first set of points.

We can use (4,70) as the second set of points.

Now, we can use the formula, 70-60 is for the top of the fraction (10)

We can do 4-6 to find the bottom, which is (-2)

Now, if we add the fraction back we get -> 10/-2 which is -5 for slope!

To find out the y intercept, it in simple words is "What is y when x is 0?".

We can do that by using the slope intercept formula: .

Once we insert our slope which is -2 we get:

We can now substitute a point, lets use (6,60) so we can find out b.

We now get the equation: .

If we solve for that we get 90!

Once we input that, we get,

Now we put in x as 0 and we get our y intercept as 90!

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof
