How do i find the slope, y-intercept, and coordinates of (-1,7) (0,5)?

The slope for the given points is - 2  , and  y- intercept is 5

Step-by-step explanation:

Given points as :

( - 1 , 7 )  and  ( 0 , 5 )

Now slope of line in points form as

Slope = m =

or, m =  

or, m = - 2

so, Slope of line is - 2

Now equation of line is given as

y - = m × ( x -   )

or, y - 7 = ( - 2 ) × ( x + 1)

or, y - 7 = - 2 x - 2

Or, equation of line is

y = - 2 x + 5

Now, for y - intercept , x = 0

So, from line equation

y = - 2 × 0 + 5

Or, y = 0 + 5

∴ y = 5

Hence The slope for the given points is - 2  , and  y- intercept is 5  Answer

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
