Let p be the plane in space that intersects the x-axis at −5, the y-axis at −2, and the z-axis at 5. Find a vector v¯¯¯ that is
Lana71 [14]

Let P be the plane that intersects

  • x-axis at point (-5,0,0);
  • y-axis at point (0,-2,0);
  • z-axis at point (0,0,5).

Write the equation of the plane P:

\left|\begin{array}{ccc}x-(-5)&y-0&z-0\\0-(-5)&-2-0&0-0\\0-(-5)&0-0&5-0\end{array}\right|=0\Rightarrow \left|\begin{array}{ccc}x+5&y&z\\5&-2&0\\5&0&5\end{array}\right|=0.

Then

-10(x+5)+10z-25y=0,\\ \\2(x+5)-2z+5y=0,\\ \\2x+5y-2z=-10.

The coefficients at variables x, y and z are the coordinates of perpendicular vector to the plane. Thus

\vec{v}=(2,5,-2)\perp P.

Answer: \vec{v}=(2,5,-2).

What is the slope of this line ?
lidiya [134]

Answer:

The slope of this line is 7/4 or 1.74 in decimal form.

m = 7/4 OR m = 1.75

Step-by-step explanation:

slope = y^2 - y^1 / x^2 - x^1

Let's pick any two points from the graph: (-1, -3) and (3, 4)

m = y^2 - y^1 / x^2 - x^1

m = 4 - (-3) / 3 - (-1)

m = 4 + 3 / 3 + 1

m = 7/4

m = 1.75
