Question

The speed of a motorcycle is changing according to the equation y = -2x +30, where x = the time in seconds

Answer 1

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

$y=mx+b$

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.
