Answer: B
Step-by-step explanation:
Answer:
y = -5/3x - 3
Assuming this is a linear function
Step-by-step explanation:
1. Use (y2-y1)/(x2-x1) to find the slope of the equation, assuming it is a linear function.
(-3-2)/(0+3) = -5/3 <--- slope
2. The y-intercept is going to be the (0, -3) point, since the point is directly on the y-axis.
3. Put both of those values into the new equation
y = -5/3x - 3
Answer:
Step-by-step explanation:
So we have the equation:
And we want to write it in terms of m.
So, let's subtract b from both sides:
Now, let's divide both sides by x:
And we're done!
Given the graph y = f(x)
The graph y = f(cx), where c is a constant is refered to as horizontal stretch/compression
A horizontal stretching is the stretching of the graph away from the y-axis.
A horizontal compression is the squeezing of the graph towards the
y-axis. A compression is a stretch by a factor less than 1.
If | c | < 1 (a fraction between 0 and 1), then the graph is stretched horizontally by a factor of c units.
If | c | > 1, then the graph is compressed horizontally by a factor of c units.
For values of c that are negative, then the horizontal
compression or horizontal stretching of the graph is followed by a
reflection across the y-axis.
The graph y = cf(x), where c is a constant is referred to as a
vertical stretching/compression.
A vertical streching is the stretching of the graph away from the x-axis. A vertical compression is the squeezing of the graph towards the x-axis. A compression is a stretch by a factor less than 1.
If | c | < 1 (a fraction between 0 and 1), then the graph is compressed vertically by a factor of c units.
If | c | > 1, then the graph is stretched vertically by a factor of c units.
For values of c that are negative, then the vertical compression or vertical stretching of the graph is followed by a reflection across the x-axis.
