Which equation is a point-slope form of the equation of this line?

1 answer:

3 0

The y-intercept is easily read: it is (0,5). The slope, m, is m = rise / run

7-1
= ----------- = 6/3 = 2
1-(-2)

Thus, the eqn of the line is y = 2x + 5. In point-slope format, y-5=2(x-0).

Ratling [72]

Answer:

L = 70

W = 32

Step-by-step explanation:

P = 2L + 2W

P 204 feet

W = x

L = 2x + 6

P = 2L + 2W

P = 2*(2x + 6) + 2*x

P = 4x + 12 + 2x

P = 6x + 12

But we know that P = 204 So 6x + 12 = 204

6x + 12 = 204 Subtract 12 from both sides

6x + 12 - 12 = 204 - 12 Collect like terms on the right

6x = 192 Divide by 6

x = 192/6

x = 32

Answer

W = 32

L = 2*W + 6

L = 2*32 + 6

L = 64 + 6

L = 70
