Option D: y-7=2(x+1) is the equation of line in point - slope form

Explanation:

Given that the slope is m=2 and the point (-1,7)

We need to determine the equation of the line in point - slope form.

The point - slope form can be determined using the formula,

y-y_1=m(x-x_1)

Let us substitute the point (-1,7) and the slope m=2 in the above formula.

Thus, we have,

y-7=2(x-(-1))

Simplifying the terms, we get,

y-7=2(x+1)

Thus, the equation of the line in point - slope form is y-7=2(x+1)

Therefore, Option D is the correct answer.

Lauren spent 3/5 of her money on a refrigerator. The refrigerator cost $756. How much money did she have left?
Lelechka [254]
Fractions are the part/whole.  We can set this up to be...

3/5 = 756
756 x5/3 = 1260.

if she had 1260 to begin with and spent 756, she would have 504.00 left.
