For the 2nd equation u have to divide 3 for both sides so y can be alone so it will be y=3x+6
Answer:
When a line intersects, the resulting angles form a pair of parallel lines. Corresponding angles are akin to each other. One way to get the appropriate angles is to draw a letter F on the diagram.
Step-by-step explanation:
Hope this helps.
Answer:
y = -2x -3
Step-by-step explanation:
- the altitude trough F is a perpendicular line to the line DE
- find slope of line DE
D ( x2 = -5, y2 = -1); E (x1 = 3, y1 = 3)
slope m = (y2-y1) / (x2-x1) = (-1-3) / (-5-3) = -4/ -8 = 1/2
-find equation of the altitude trough F
lines that are perpendicular have the slope negative reciprocal (negative reciprocal of 1/2 is -2)
y= -2x +b , for point F(1, -5)
-5 = -2*1 +b, add 2 to both sides
-5 +2 = b, combine like terms
-3 =b
equation of the altitude trough F is y = -2x -3
=-8y-12=52
+12 +12
-8/-8y=64/-8
y=-8
