Find the slope and y-intercept of the graph of the linear equation y= -4x

1 answer:

5 0

Answer:

Slope = -4

Y-intercept = 0

Step-by-step explanation:

the equation of the line is written in slope-intercept form: y = mx + b where m = slope and b = y-intercept

To find the slope, look at the number before x.

And for y-intercept, take a look at the number at last

(If there isn’t no y-intercept, that indicates that the y-intercept is 0)

Hope this helps!

Love you.

Find an equation of the plane. The plane through the points (0, 9, 9), (9, 0, 9), and (9, 9, 0) Incorrect: Your answer is incorr

Andrei [34K]

Answer:

The equation of the plane is represented by $\frac{1}{18}\cdot x + \frac{1}{18}\cdot y + \frac{1}{18}\cdot z = 1$ .

Step-by-step explanation:

Algebraically speaking, a plane can be represented by following vectorial product:

$(a,b, c)\,\bullet\,(x,y,z) = 1$ (1)

Where:

$a$ , $b$ , $c$ - Plane coeffcients.

$x$ , $y$ , $z$ - Coordinates.

We need three distinct points to determine all coefficients. If we know that $(x_{1},y_{1},z_{1}) = (0,9,9)$ , $(x_{2},y_{2}, z_{2}) = (9,0,9)$ and $(x_{3},y_{3},z_{3}) = (9,9,0)$ , the system of equations to be solved is:
