y = 9 because 9 over 3 simplified is 3 and 3 plus 6 equals 9
1. Find the equation of a line passing through the point (4, –7) parallel to the line 4x + 6y = 9.
2. Find the equation of a line passing through the point (–3, 8) perpendicular to the line 2x – 7y = –11.
3. Find the equation of a line passing through the point (5, 4) perpendicular to the line –4x – 3y = 6.
4. Find the equation of a line passing through the point (–2, –1) perpendicular to the line 5x + 6y = –6.
5. Find the equation of a line passing through the point (–7, 2) parallel to the line –4x + 10y = –5.
6. Find the equation of a line passing through the point (8, –9) perpendicular to the line 3x + 8y = 4.
Answer:
B
Step-by-step explanation:
6x - 6/3 = 2x - 2
6x - 2 = 2x - 2
6x - 2 + 2 = 2x - 2 + 2
6x = 2x
6x - 2x = 0
4x = 0
Divide both sides by 4
4x/4 = 0/4
x = 0
The equation has exactly one solution.
Reasons are that it is an algebraic linear equation where the unknown variable, x has highest power as 1.
Also after solving for x, we see that we got only one value or solution for x
