.........
Answer:
(1, -2) Option A in your list of possible answers
See attached image.
Step-by-step explanation:
We need to graph the lines by using a couple of points on the plane for each equation.
For example:
the points (0, -3) and (3, 0) for the line y = x - 3
and the points (0, 1) and (-1, 4) for the line y = - 3 x + 1
Please see the lines in the attached image, and notice that they intersect at the point (1, -2), which gives you the solution for the system.
Answer:
Option B
Step-by-step explanation:
Given equation is

The original graph would be

From this transformations done are
a) horizontal shift of 5 units to the left
b) shrink vertical by scale factor 1/5
c) vertical shift of 2 units up
Hence option A is not right
Option B is right.
Similarly C and D are not right.
Answer:
4:3
Step-by-step explanation:
a+b = 7 units
a = 4 units
b = 7 - 4 units
Thus,
a:b
