Which of the following statements is true about the graph of the equation 2y-3x=-4 in the xy-plane? Explain step by step how you

sertanlavr [38]

D. It has a positive slope and negative y- intercept.

Step-by-step explanation:

2y -3x = -4

We can rewrite the equation in the form of y = mx+ b where m is the slope and b is the y - intercept as,

2y = 3x- 4

Dividing all the terms by 2, we will get,

2y/2 = 3x/2 - 4/2

y = (3/2)x -2

So the slope is 3/2 which is positive and y-intercept is -2 which is negative.

Describe the transformation that takes f(x)=x+1 to g(x) = -x+4. Will Mark Brainliest.

lions [1.4K]

Answer:

Reflection across y axis

Translate up by 3 units

Step-by-step explanation:

Given

$f(x) = x + 1$

$g(x) = -x + 4$

Required

Describe the transformation from f(x) to g(x)

First, take a reflection of f(x) across the y axis.

So f(x) becomes f(-x)

$f(x) = x + 1$ when reflected

$f(-x) = -x +1$

Next, translate f(-x) up by 3 units to give g(x)

$g(x) = f(-x) + k$

Where

$k = 3$

$f(-x) = -x +1$

$g(x) = -x + 1 + 3$

$g(x) = -x + 4$

Hence, the transformation from f(x) to g(x) includes:

Reflection across y axis

Translate up by 3 units
