write an equation for the line that passes through the given point and has the given slope m (4,-5);m= -1/4

EastWind [94]

-------------------------------------------------------------------------------------------------------------

Answer: $\textsf{y = -1/4x - 4}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{Slope = -1/4, Point through = (4, -5)}$

Find: $\textsf{Equation for the line that passes through the given point}$

Solution: In order to get the equation, we need to first use the point-slope form to help us sort out our information and then we solve for y.

Plug in the values

$\textsf{y - y}_1\textsf{ = m(x - x}_1\textsf{)}$

$\textsf{y - (-5) = -1/4(x - 4)}$

Simplify and solve for y

$\textsf{y + 5 = -1/4(x - 4)}$

$\textsf{y + 5 = -1/4x + 1}$

$\textsf{y + 5 - 5 = -1/4x + 1 - 5}$

$\textsf{y = -1/4x - 4}$

Therefore, the final answer would be that the equation that has a slope of -1/4 and passes through (4, -5) is y = -1/4x - 4.

Could someone please explain how to plot the x-intercept of the first equation and what the answer would be?

Elis [28]

Answer:

You would start in the middle of the number line, move right to positive 4x then move up 2 units to land right in line with 2y this is where your plot would be.

PLEASE HELP!! Find the volume of the sphere rounded to the nearest hundredth

Studentka2010 [4]

Answer:

Step-by-step explanation:

The volume for a sphere is

$V=\frac{4}{3}\pi r^3$ . Our radius is 21 inches, so

$V=\frac{4}{3}\pi (21)^3$ and

$V=\frac{4}{3}\pi (9261)$ . Multiplying straight across the top, using the fact that 3.14 is pi:

$V=\frac{116318.16}{3}$ and divide to get that

V = 38772.72 in^3
