Answer:
A line a and line b
Step-by-step explanation:
Lines b and c are parallel (no intersection points), so the system will have no solutions.
Lines b and d are parallel (no intersection points), so the system will have no solutions.
Lines c and d coincide (infinitely many intersection points), so the system will have infinitely many solutions.
Lines a and b will intersect after extension, so the system of these two equations will have only one solution.
Line A is parallel to line B if line A and B have the same slope and have the same or different y-intercept.
Convert the standard form equation to slope-intercept form as it will be easier to see the slope.
Solve for y.
4x + 2y = 0
2y = -4x <-- Subtract 4x from each side
y = -2x <-- Divide both sides by 2
In the slope-intercept form y = -2x, a y-intercept of 0 is implied
Now find a slope-intercept form equation that has the same slope as y = -2x
So, the answer is C y = -2x + 3.

Answer:
y= 9x + 8
Step-by-step explanation:
Answer:
y = 1x -3
4 4
Step-by-step explanation:
m= 4 -> 1
4
y-y1 = m(x-x1)
y+1 = m(x-2)
y+1 = 1(x-2)
4
y+1 = 1x -1
4 2
y = 1x - 3
4 4
