what is the given point and slope
1 answer:
Answer:
3x - y =13
Step-by-step explanation:
- y - y1 = m(x - x1)
- y - 2 = m(x - 5)
- distribute
- y - 2 = 3x - 15
- jump -2 across the equal sign and change the sign
- y = 3x - 15 + 2
- combine like terms
- y = 3x - 13
- use this equation to find the standard form
- y = 3x - 13
- jump the x and change the sign
- -3x + y = -13
- x must be positive, so change the sign of everything
- 3x - y = 13

12x - 6 = 3x + 30
12x = 3x + 36
9x = 36
x = 4
the value of x is 4
