Answer:
y=-1.5
X=1.75
Step-by-step explanation:
Yuh arrange the equations in order for easy subtracting of the equations.
-2y=0.5-2x. divide both sides by 2 to get y=-x-0.25.
6x+3y=6
3y=-6x+6 then divide both sides by three to get y
y=-2x+2
now arrange
y=-2x+2
y=-x-0.25 then multiple both equations by the cordinates of X value to eliminate x
Recognize that parallel lines have the same slope. Then:
Method 1: write y = 2x + c and find c from the given information:
y = 2x + c becomes 0 = 2(-2) + c, so that c = 4. Then y = 2x + 4 (answer)
Method 2: Slope is 2 and a point on the line is (-2,0):
Use the point-slope formula: y - 0 = 2(x+2), or y = 2(x+2), or y=2x+4 (ans)
-2 + 2.5= 0.5 and -7 + (-1.5) = -8.5
so B is at (0.5, -8.5)
