Answer:

b

Step-by-step explanation:

a pex

Slope of the equation y + 2 = 3 ( x - 7 ) is  3.

The correct answer is option

B. The slope is 3 and (7,-2) is on the line.

Slope of the equation

There are two ways we can find the slope-intercept form for this equation. Which would be to convert to standard form, or convert to slope-intercept form. In this case, I'll be converting the equation to slope-intercept form.

Slope Intercept Form Formula:

y = mx + b

Now, we'll write out our original equation and covert it.

Original Equation :

y + 2 = 3 ( x - 7 )

Simplifying the above equation

y = 3x - 23

From here we can just spot which number is m and that number is 3.

If you want to know how that image is graphed, I attached an image to the answer.

So, the slope of the equation y + 2 = 3 ( x - 7 ) is  3.

Therefore, the correct answer is option

B. The slope is 3 and (7,-2) is on the line.
