Write an equation (in slope-intercept form) of the line that passes through (0, 3) and (−5, 2.5).
Paladinen [302]

The equation of the line passing throught the points A(x_A,y_A) and B(x_B,y_B) has a form

\dfrac{x-x_A}{x_B-x_A}=\dfrac{y-y_A}{y_B-y_A}.

Now the equation of the line passing through points (0, 3) and (−5, 2.5) is

\dfrac{x-0}{-5-0}=\dfrac{y-3}{2.5-3}.

Simplify it:

\dfrac{x}{-5}=\dfrac{y-3}{-0.5},\\ \\0.5x=5(y-3),\\ \\5x=50y-150,\\ \\x=10y-30,\\ \\10y=x+30,\\ \\y=0.1x+3.

This equation is in slope-intercept form.

Answer: y=0.1x+3.

The midpoint AB is M (-1,1). If the coordinates of A are (-6,-3), what are the coordinates of B
Ratling [72]

Answer:

coordinates of B is ( 4,5)

Step-by-step explanation:

If there two points (x1,y1) and (x2,y2) on a plane then coordinates of mid point is given by

m = (x1+x2)/2  , (y1+y2)/2

Given

m = (-1,1)

A= (-6, -3)

we have to point b

let point b be (x,y)

Then m (-1,1) is given by (-6+x)/2 , (-3+y)/2

(-6+x)/2 = -1

-6 + x = 2*-1 = -2

x = -2+6 = 4

also

(-3+y)/2 = 1

=> -3 + y = 2

=> y = 2 + 3 = 5

Thus , coordinates of B is ( 4,5) answer
