Answer:
Y = 3x - 2 will be the answer.
Step-by-step explanation:
A line has been graphed in the figure attached.
It passes through two points ( 1,1) and (2,4)
Y-intercept of the given line is (-2)
Since equation of a line in the intercept form is
y = mx + c
where m = slope and c = y-intercept
and slope m =
Therefore, slope m =
=
Therefore, equation of the given line will be y = 3x - 2

Answer:
A.
D. No, because one x-value corresponds to two different y-values.
Step-by-step explanation:
If you were to vertically stretch the quadratic parent function, the correct answer would be "A," because you are stretching upwards, which in turn, also changes the y-values.
As you can see in the table, the x-value of 3 repeats, which cannot occur. Each input (x-value) can go to only one output (y-value). As a result, the table does not represent a function.
