Write an equation that passes through a pair of points

Phoenix [80]

Answer:

C. $y = -x + 2$

Step-by-step explanation:

First, find the slope, m, of the line that passes through the two given points.

Slope = $\frac{rise}{run} = \frac{-2}{2} = -\frac{1}{1} = -1$

Next, determine the y-intercept, b.

The y-intercept is where the line intercepts the y-axis. The line intercepts the y-axis at y = 2. Therefore, b = 2.

Now, to get an equation of the line, substitute m = -1, and b = 2 in $y = mx + b$ .

✅The equation would be:

$y = -1x + 2$

$y = -x + 2$

Complete factorization of x^3 - 4x^2 + x - 4

Pachacha [2.7K]

Step-by-step explanation:

x³ - 4x² + x - 4

= x²(x - 4) + (x - 4)

= (x² + 1)(x - 4).

Since the quadratic factor (x² + 1) is irreducible any further, this is our answer.

For f(x)=x/4-3 and g(x)=4x^2+2x-4 find (f+g)(x)

blondinia [14]

$f(x)=\dfrac{x}{4}-3=\dfrac{1}{4}x-3\\\\g(x)=4x^2+2x-4\\\\(f+g)(x)=f(x)+g(x)=\dfrac{1}{4}x-3+4x^2+2x-4\\\\=4x^2+\left(\dfrac{1}{4}x+2x\right)+(-3-4)=4x^2+2\dfrac{1}{4}x-7$
