Answer:
y=2x+1
Step-by-step explanation:
Parallel = gradients are the same
Example: y=2/4x+5
Perpendicular = gradients are the inverse of each other
Example: y= -4/2x+1
Any equation would be correct unless the gradient is 2/4 or -4/2
Answer:
Solve for x, y, and z. 1st Equation: 2x + 2y + 4z = 48. 2nd Equation: 2x + 9y + 7z = 105. 3rd Equation: x + 4y + z = 37. Subtract the 2nd Equation from the 1st Equation. This will eliminate the variable “x”.
Step-by-step explanation:
It would be the first graph
That is because the 2nd and 3rd graphs start at a point close to (0,-2) but it is not the correct point.
Now using (0,0) as a solution plug it in for the x and y values like so
0 <−3(0)−2 = 0 < -2
0 ≤ 0 −2 = 0 ≤ -2
This does not work so solutions from (0,0) up cannot be solutions, so the first graph must be the right answer.
