Graphing linear equations 3x -1/2y =2

y = 6x-4

Step-by-step explanation:

3x - 1/2 y =2

We need to solve for y to get the equation in slope intercept form

Subtract 3x from each side

3x-3x - 1/2 y =-3x+2

-1/2 y = -3x+2

Multiply each side by -2

-2*-1/2 y = -2*(-3x+2)

y = -2*(-3x+2)

Distribute

y = 6x-4

The slope is 6 and the y intercept (where it crosses the y axis) is -4

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
