Graph the linear equation. Find three points that solve the equation, then plot on the graph. -3x+2y=2
aleksandrvk [35]

First you need to put the equation into slope form which is y = mx + b

-3x + 2y = 2

2y = 3x + 2

y = 1.5x + 1

In this equation the y-intercept is 1 and the slope is 1.5 or 3/2.

To graph the line you can start at the y-intercept then move up 3 and to the right 2 or down 3 and to the left 2.

Three points are (2, 4) , (-2 ,-2), (4, 7).

Hope this helps! Mark as Brainliest please! :)))

Which function represents a reflection of f(x) = Three-eighths(4)x across the y-axis? g(x) = NegativeThree-eighths (one-fourth)
nignag [31]

The function which represents a reflection of f(x) is

g(x) = Three-eighths (4)^{-x} ⇒ last answer

Step-by-step explanation:

Let us revise the reflection across the axes

  • If the function f(x) reflected across the x-axis, then its image is g(x) = - f(x)
  • If the function f(x) reflected across the y-axis, then its image is g(x) = f(-x)

∵ Three-eighths = \frac{3}{8}

∴ f(x)=\frac{3}{8}(4)^{x}

∵ f(x) is reflected across the y-axis

- That means the sign of x coordinates of the points on the graph will

  change to opposite

∴ x will change to -x

∴ g(x)=\frac{3}{8}(4)^{-x}

The function which represents a reflection of f(x) is

g(x) = Three-eighths (4)^{-x}
