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.

5/7 = non orange marbles
?/21 = chances to pick a non blue
21/7 = 3
5x 3 =15
15/21
Answer:
31.5 cm²
Step-by-step explanation:
Calculate area of a triangle with this formula:
Area = 
base * height
Substitute in known values
Area = 7 * 9
Multiply 7 by 1/2
Area = 3.5 * 9
Multiply
Area = 31.5 cm²
Hope this helps :)
