The equations give you information as to where to plot points.
For y = -x + 1, you know the slope is -1, and the line intersects the y-axis at (0, 1). The y-axis is the vertical line; to plot (0, 1), find 1 on the vertical line and mark it. Now, the slope is -1; that means the line will slope downwards. To plot more points, count 1 unit down from (0, 1) and 1 unit to the right. You should end up at (1, 0).Connect those and you have a line.
For y = -2x + 4, the slope is -2 (so it will also slope downwards), and the y-intercept is 4. Find (0, 4) and plot it. The -2 tells you to count 2 units down (instead of 1 like we did for the last equation) and 1 over. That is the second line.
I hope this helps.
Answer:
Step-by-step explanation:
15n - 45/5 = 6n - 9...reduce any fractions
15n - 9 = 6n - 9 ...subtract 6n from both sides
15n -9 - 6n = 6n - 6n - 9...combine terms
9n - 9 = -9....add 9 to both sides
9n - 9 + 9 = -9 + 9...combine terms
9n = 0....divide both sides by 9
n = 0/9 which = 0

Answer:
the preimage will be congruent to the image
Step-by-step explanation:
8.a)
A= (1,1) A’= (3,3)
B= (4,6) B’= (12,18)
C= (6,1). C= (18,3)
8b.)
A= (1,1) A’(0,5,0.5)
B= (4,6) B(2,3)
C= (6,1). C(3,0.5)
Hope this helped ! :)
