First, plot the y-intercept, which is (0,1).
Next, put your pencil point at this y-intercept (0,1). Move it 1 space the right and from there 2 spaces up. Plot this new point.
Last, draw a line thru the two points you plotted.
Answer:
816.8
Step-by-step explanation:
For each rotation of the tire, the wheel axle moves forward by a distance equal to the circumference of the tire.
Here, that circumference is C = pi*d, where d is the wheel diameter:
C = pi(26 in) = 26 pi inches.
The distance covered in 10 rotations of the wheel is thus 10(26 pi inches) = 260 pi inches. To the nearest tenth, that's 816.8 inches.
There are 30 boys in the competition. You can find it by first dividing 42 by 7 which is 6, then you multiply 6 by 5 to get 30.
The equation of this line is given by:
y = -1/2x + 1.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Given two points, the slope is given by <u>change in y divided by change in x</u>. In this problem, we have points (0,1) and (2,0), hence:
m = (1 - 0)/(0 - 2) = -1/2.
Point (0,1) also means that the y-intercept is of b = 1, hence the equation of this line is given by:
y = -1/2x + 1.
