Explain in your own words how you would graph the equation y = -4x + 25

Answer:

See below

Step-by-step explanation:

First, I would choose three different points with some distance between. Let's do x = -5, x = 0, and x = 5. Next, I would plug those numbers into the equation, like so:

y = -4(-5) + 25 = 20 + 25 = 45

y = -4(0) = 25 = 25

y = -4(5) + 25 = -20 = 25 = 5

Next, I would plot the points [(-5, 45), (0, 25), (5, 5)] on an x-y graph. Finally, I would take a ruler, line it up with the three points, and draw a line through those three points, extending from one side of the graph to the other to show the equation is continuous.

The slope of the function, f(x) can be determined by choosing two sets of ordered pairs from the table and substituting their values into the slope formula.

Let (x1, y1) = (0, -1)
(x2, y2) = (1, 7)

Plug these values into the slope formula:

m = (y2 - y1)/(x2 - x1)

m = [7 - (-1)] / [1 - 0]
m = (7 + 1) / 1
m = 8/1 or 8.

Therefore, the slope of f(x), m = 8.

The y-intercept of the function, f(x) is given by (0, -1), as it is the point on the graph where it crosses the y-axis. It is also the value of y when x = 0.

The equation of the linear function, f(x) is:
f(x) = 8x - 1.

Given the slope-intercept form, y = mx + b, where m represents the slope of the line, and b represents the y-intercept:

The function, g(x) = 3x - 2 has a slope of 3, and y-intercept of -2.

Comparing the slope and y-intercept of the two functions, f(x) and g(x):

The slope of f(x), m = 8 is greater and steeper than the slope of g(x), m = 3. The y-intercept of f(x), b = -1 is greater than the y-intercept of g(x), b = -2.

Attached is a screenshot of the graph of both lines, including their y-intercepts. The blue line is g(x) = 3x - 2, and the red line is f(x) = 8x - 1.

Gemiola [76]

Answer:

x² + (y-74)² = 4900

Step-by-step explanation:

Circle equation: (x-h)² + (y-k)² = r²

"h" refers to horizontal shifts while "k" refers to vertical shifts. If the center of the wheel is directly above the origin of the rectangular plane and the entire wheel is 4 ft. from the ground then:

  • h = 0
  • k = 74 (the radius + 4 ft.)
  • r = 70

So plugging those into the equation of circles, we get the answer above.
