Question

Can someone please help me with this

Answer 1

point 1 = ( -1 , 5 )       point 2 = ( 5 , -5 )

equation of a line:       y = mx + b

Find Slope (m):

( 5 - (-5)) / (-1 - 5))

= 10 / -6

= -3 / 2

slope = -3/2

Find y-intercept (b):

y = mx + b

y = -3/2 * x + b

5 = -3/2 * -1 + b          <--------------  use the x and y coordinate of one of the                                                                                  .                                                                        points. I used point 1 ( -1 , 5 )

b = 7/2 or 3.5

Assemble:

y = -3/2 * x + 3.5
