Answer:
Step-by-step explanation:
y = 4/3x
you can see the line passes through (0,0)
the next point it passes through is (3,4)
(y2-y1)/(x2-x1)
(4 - 0)/(3 - 0)
4 / 3
the slope = 4/3
meaning it goes up 4 and right 3 from point to point
Y=mx+b
parallel lines will have the same slope.
using the points (-4,6) and the slope for the parallel line -3 we can find b (the y intercept) for the line.
6 = (-3)(-4) + b
6 = 12 + b
-12 + 6 = -12 + 12 +b
-6 = b
so the line that runs through points (-4,6) and parallel to y= -3x+4 is:
y = -3x -6
Answer:
The second graph
Step-by-step explanation:
each of the points you listed are graphed on there.
Answer: y = |x - 4| − 10
Step-by-step explanation: Reflection over the y-axis switched the first sign and -2 was added to -8 due to the translation 2 units down.
Hope this helps!
18/12=21/Y | :3
6/12=7/Y
Y= 7*12/6
Y=7*12/6=14
18/12=X/10 | :2
X= 18*10/12
X=3*10/2
X=15
