Help me please i do not understand it.

1 answer:

3 0

Answer:y = 2x + 4

Explanation:

1) The slope - intercept form is of the kind y = mx + b, where m is the slope and b is the y-intercept.

2) Given two points you can find the slope (using the two points) and then the equation using one of the points.

3) slope = m = Δy / Δx

points given (3,10) , (0,4)

m = [y2 - y1] / [x2 - x1] = [10 - 4] / [3 - 0] = 6 / 3 = 2

4) equation

y - y2
-------- = m
x - x2

y - 4
---------- = 2
x - 0

=> y - 4 = 2 (x - 0)

y - 4 = 2x

y = 2x + 4

If the area of a square is 100 cm2, what is the perimeter?

Vitek1552 [10]

Answer:

Step-by-step explanation:

To find the perimeter, first we need to find the side lengths.

If 100 cm is the area then we need to find what number squared is 100

10 x 10 = 100

So 10 is the side length. P= s + s + s +s

10 + 10 + 10 +10 = 40
