The speed of a motorcycle is changing according to the equation y = -2x +30, where x = the time in seconds
1 answer:
Answer:
The given line y = -2x +30 is a straight line as it is written in the
form y = mx + b.
The graph of the line y = -2x +30 is also straight and attached below.
Step-by-step explanation:
Given the equation
y = -2x +30
We know that the slope-intercept form of the line equation is
Where m is the slope and b is the y-intercept
- The graph of y=mx+b is a straight line as it is the line equation.
Writing the equation in the slope-intercept form
y = -2x +30
y = mx + b
Thus,
m = -2
b = 30
Thus, the given line y = -2x +30 is a straight line as it is written in the
form y = mx + b.
The graph of the line y = -2x +30 is also straight and attached below.
