Answer:
y=2x-3
Step-by-step explanation:
First we find the y-intercept of this graph whic in this case is -3. Then we plot two pints on the graph and caculate the rise over run which is 2/1=2. Finally, we get the equation- y=2x-3.
we know that
the formula to calculate the slope between two points is equal to
in this problem we have
substitute the values in the formula
therefore
<u>the answer is the option</u>
Answer:
Reflected about the y-axis and then rotated 90° counterclockwise
Step-by-step explanation:
(x , y) to (-x , y) --> reflected over y-axis
then (-x , y) --> (-y, -x) -->90 degrees rotation counterclockwise
So answer is the last one
Reflected about the y-axis and then rotated 90° counterclockwise
Answer:
y =
Step-by-step explanation:
We are given the point (3, 10).
The second point is 2 on the x-axis and -7 on the y-axis. So our second point is: (3 + 2, 10 - 7) which is (5, 3).
Our formula for slope is m = =
So, our equation would be =
Using the standard formula of a line, y = mx + b, we can substitute for the slope, m.
y = + b
Now, we can substitute a point on the line to determine the y-intercept:
Using the point (3, 10),
10 = + b
b = 10 +
b =
So our full equation is: y =
