Answer:
Graph of the new function will be vertically stretched by 2 units.
Step-by-step explanation:
A linear function is represented by the equation, y = 
This function has the slope =
and y-intercept = 4
If this function is stretched vertically by 'k' the the equation of the new function will be,
y = 
y =
---------(1)
If the slope of this equation is changed to
,
New equation of the function will be,
y =
---------(2)
Comparing equations (1) and (2),
a = 2
Therefore, graph of the new function will be stretched vertically by 2 units.
$20 is the base cost (y intercept)
$0.50 is the cost per ride (slope)
Plug into an equation
Y = 20 + 0.50x
35 = 20 + 0.50x
15 = 0.5x, x = 30
Solution: 30 rides
It is the division property of equality. You divide by 5 each side of the equation to isolate x.
The image would then be in quadrant 3 because say you "folded" the coordinate plane across the x-axis, then the point attached onto the other side of the plane, the point would be in the 3rd quadrant.
