The equation of a line is usually written in what's called <em>slope-intercept form</em>.
Slope-intercept form is written as y = mx + b where m = slope and b = the y-intercept.
The slope of a line can easily be found just by using two points on the line. The slope is equal to the rise over the run, or the difference in y over the difference in x, between the two points.
The y-intercept of the line is the point at which it intersects the y-axis. (The vertical axis.) All points on the y-axis have an x coordinate of 0, so we would then add or subtract the rise and run to a point on the line until we reached x = 0.
Fortunately, we already have this point! It's (0, -2)!
Now we just need to put our slope and y-intercept into the equation.
And to test if a point is on this line, just plug in the x and y coordinates and see if the equation is true!
The area available to the goat is 3/4 of a circle with 6 ft radius plus 2/4 of a circle with 3 ft radius.
A = (3/4)π*(6 ft)² + (1/2)π*(3 ft)²
= π*((3/4)*36 +(1/2)*9) ft²
= 31.5π ft² ≈ 98.96 ft²
The goat can roam over an area of about 99 ft².
Answer:
The slope is 3
Step-by-step explanation:
Rise / Run
3 / 1
= 3
If the 8 you’re talking about is in inches then it would be 16 feet but if it’s 8 feet then it’s 4 inches
No x does NOT equal 16. you would substitute x for 16 which gives you 16+12. That equals 28 not 30. The correct answer is x=18
