Write the equation of a line with a slope of -7/2 passing through the point 2,-4
fiasKO [112]

Answer:

y = -7/2x+3

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b  where m is the slope and b is the y intercept

y = -7/2 x+b

Substitute the point into the equation

-4 = -7/2(2) +b

-4 = -7+b

Solving for b

-4+7 = -7+b+7

3 = b

The equation is y = -7/2x+3

PLEASE HELP!!!!!!!<br> Find the Volume of the sphere rounded to the nearest hundredth
Volgvan

Answer:

14130 yd^3

Step-by-step explanation:

The volume of a sphere is

V = 4/3 pi r^3

The diameter is 30 so the radius is d/2 = 30/2 = 15

V = 4/3 pi (15)^3

V = 4500 pi

Letting pi = 3.14

V = 14130 yd^3

Which is an equation of the line with slope –3 and passes through (2, –1)?
vodka [1.7K]

Answer:

d)  3x + y = 5

Step-by-step explanation:

The standard equation of a line with slope and a point is given by:

y = mx + b

We know that

m=-3

Putting the value of slope

y = -3x+b

To find the value of b, we will put the point in the equation

-1 = (-3)(2)+b

-1 = -6 + b

-1+6 = b

b = 5

Putting the values of b and m in standard equation

y = -3x+5

Can also be written as:

3x+y = 5

Hence,

Option d: 3x + y = 5 is the correct answer ..
