Answer:
Step-by-step explanation:
One of the given points is the y-intercept. That means you can write the equation in slope-intercept form once you have found the slope.
m = slope = (change in y)/(change in x) = (y2 -y1)/(x2 -x1)
= (-3 -(-2))/(0 -(-3)) = -1/3
The slope-intercept form for slope m and intercept b is ...
y = mx +b
For slope -1/3 and intercept -3, the equation is ...
y = -1/3x -3
Answer:
Option 3
Step-by-step explanation:
we are given the graph of a parabola
with vertex at (0,-1) and symmetrical about y axis and also open up.
Hence the equation of the graph would be transformation of
by a vertical shift of 1 unit down.
So new equation after transformation would be
Or
Hence option 3 is right choice.
Verify:
Put Solving the equation we get
In the graph x intercepts are the same as -1 and 1
Hence our answer is right.
Answer:
