The answer you want is 20!
To get the equation of a line, you can use the following:
y - y1 = m (x - x1)
Where:
- m is the slope (2)
- y1 is the y coordinate of a point (1, -5)
- x1 is the x coordinate of the same point (1, -5)
Just substitute in the values:
y - y1 = m (x - x1)
y - (-5) = 2(x - 1) <em>( - - 5 = + 5 )</em>
y + 5 = 2(x - 1)

Answer:
B. y + 5 = 2(x - 1)
Answer: a set of all possible inputs for the function.
Step-by-step explanation:
2x + 3y = 23...........................(1)
3x - y = 7 Multiply by 3:-
9x - 3y = 21 Adding this to equation (1):-
11x = 44
x =
Plug this into equation (1):-
2(4) + 3y = 23
3y = 15
y = 5
Answer is x = 4, y = 5
Since the triangle is isosceles, the angles that are not on the 87 are both equal.
The other 2 angles can be solved like this
2x + 87 = 180
2x = 180 - 87
2x = 93
x = 93/2 = 46.5 degrees or B
