Given the slope of y+2=3(x-7) and a point on the line
zaharov [31]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

m = 3

(7, -2)

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

The equation given is in point-slope form.

⸻⸻⸻⸻

y - y_1 = m(x-x_1)\\\\m-\text{slope}\\\\(x_1,y_1)-\text{point}

⸻⸻⸻⸻

The '3' is in the 'm' spot.

The y value is '-2', (y -(-2)) and the 'x' value is 7.

The point of the line is (7, -2) and the slope is 3.

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.

How would you do this problem
ICE Princess25 [194]
If line BC is congruent to line BD then angles C and D are also congruent
so you would set up the problem to find <em>x </em>as:
5x-19=2x+14
   +19      +19
____________
5x=2x+33
-2   -2
_____________
3/3x=33/3
____________
x=11
Just pug in x to the equations to solve the rest
