Answer:
D' (1, 3)
Step-by-step explanation:
When reflected across the y = x line, the "x" and "y" coordinates switch.
If D is (3, 1), then:
x = 3
y = 1
Switch the "x" and "y" values, and rewrite as (x, y).
x = 1
y = 3
D' (1, 3)
Answer:
d = 9√2
Step-by-step explanation:
The graph should contain only straight lines but it gets tricky at the y-axis. For all negative x-values, you would make them positive (the negative of a negative number is positive. For example, -3 as a value for x would simply be 3 on the y-axis). However, once you cross the y-axis, the values for x are now positive and the positive of a negative is still negative. In other words, your x values are now all positive but your y values will be negative. The graph would increase up to the origin when on the left of the y-axis, and then decrease after you cross the axis. It should resemble an upside down “V” and the rate of change, or the slope, will always be 1.
Answer:
6/12 - 9/18 = 0
Difference usually means subtract.
Answer: If you want the graph of f(x)=3x-2 and f(x)=x-2 then
Step-by-step explanation:
the blue line is f(x)=3x-2 and the green line is f(x)=x-2
f(x) is the same thing as y so all you have to do is y=3x-2 in a graphing calculator and you will get your answer
