Question

Give the slope of y+2=3(x-7) Which one is it? A) The slope is 3 and (7,-2) is on the line ? B) The slope is 7 and (3,2) is on the line ? C) The slope is 3 and (-7,2) is on the line? D) The slope is 2 and (7,3 is on the line?

Answer 1

The answer is "Option A".

Explanation:

Given line equation:

`\to y+2=3(x-7)`

The standard equation of the line:

`\bold{y-y_1=m(x-x_1)}\\\\`

Comparing the values:

`x_1= 7\\\\y_1=-2\\\\m=3\\`

So, the points are: (7,-2) and the slope is: 3

That's why Choice "A" is correct.
