Find the equation (in slope-intercept form) of the line with the given slope that passes through the point with the given coordi
Darina [25.2K]

Answer:

y = 3/2x-2

Step-by-step explanation:

slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 3/2x+b

Substitute the point in for x and y

1 = 3/2(2)+b

1 = 3+b

1-3 =b

-2=b

y = 3/2x-2

The graph of f(x) = 18x is reflected about the x-axis and shifted upward 8 units. What is the equation of the new function, g(x)
stellarik [79]
<h3>Answer:</h3>
  • g(x) = -18x +8
  • y-intercept: (0, 8)
  • domain: (-∞, ∞)
  • range: (-∞, ∞)
<h3>Explanation:</h3>

Reflecting a function across the x-axis changes every y-value to its opposite. That is, f(x) = 18x becomes g(x) = -18x.

Shifting a function upward 8 units adds 8 to every y-value. That is, g(x) becomes g(x)+8.

The combined effect of these two transformations on f(x) is to give you ...

... g(x) = -18x + 8

You recognize this as the equation of a line in slope-intercept form, with the y-intercept being +8. That is, g(0) = -18·0 +8 = 8. The y-intercept is ...

... (0, 8)

The domain and range of any linear equation is "all real numbers," that is, ...

... (-∞, ∞).
