Each statement describes a transformation of the graph of y= x. Which statement correctly describes the graph of y= x - 13?
2 answers:
Answer:
D
Step-by-step explanation:
Refer to picture.
When graph of y = x is transformed to y = x - 13,
U can visualise it by drawing the before and after transformed graphs to compare in order to deduce the answer.
From the picture, you will realise that when x is unchanged, I'm this case I'm using points x=0 and x=13, the value of the y coordinate in the transformed graph (y = x-13) actually decreased by 13 units as compared to the original graph of y=x.
Hence the graph actually got translated 13 units in the direction of negative y axis which is option D

Answer:
y = x
Step-by-step explanation:
slope-intercept form: y = mx + b
Given: slope(m) = , point (4, -3)
We already have the value of m, but we need to find the value of b. To do this, input the given values of the slope and the point into the equation:
-3 = (4) + b
Solve for b:
-3 = (4) + b
-3 = -3 + b
0 = b
The value of b is zero. We can now write the equation:
y = x + 0
y = x
The equation written in slope-intercept form is: y = x
