write the equation of the line that passes through the given points (0,-1) and (-5,-7) Simplify your answer
USPshnik [31]

Answer:

y = 6/5 x-1  slope intercept form

6x-5y = 5  standard form

Step-by-step explanation:

We have the points  (0,-1) and (-5,-7)

We can find the slope using

m = (y2-y1)/(x2-x1)

 = (-7--1)/(-5-0)

 = (-7+1)/(-5-0)

 = -6/-5

 = 6/5

We also have the y intercept ( when x=0)  It is -1

We can use the slope intercept form of the equation y = mx+b

y = 6/5 x-1

Depending on what you mean when you say simplify your answer

We can put it in standard form  ax+by = C

Multiply both sides by 5

5y =5* 6/5 x-1*5

5y = 6x-5

Subtract 6x from each side

-6x+5y = 6x-6x-5

-6x+5y = -5

Multiply by -1

6x-5y = 5

What is the slope intercept form of the equation of the line that passes through the points (2,7) and (4,-1)
natka813 [3]

Slope intercept form is y = mx + b.

Y = coordinate y.

M = Slope

X = coordinate x.

B = y-intercept.

Slope formula: (y2-y1) / (x2-x1)

Plug in: (-1 - 7) / (4 - 2) = -4.

We can just insert the pair (2,7) as our x and y to solve b.

7 = -4(2) + b.

Solve for b.

7 = -8 + b.

-b = -8 -7

-b = -15

b = 15.

Original equation:

y = mx + b

y = -4x + 15
