How to write (7,-6); m= 1/2 in slope intercept form?

Since the question already give the slope we only need to find the y-intercept.

Slope-intercept form: y = mx + b

-6 = 1/2(7) + b

-6 = 3.5 + b

-6 - 3.5 = 3.5 - 3.5 + b

-9.5 = b

Now, we can write this in slope-intercept form.

y = 1/2x - 9.5

Best of Luck!

yep

step-by-step explanation:

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
