Determine the slope and y-intercept of a line that passes through the points (-2, 12) and (4, -15).

Step-by-step explanation:

y²-y¹/x²-x¹

(-15)-(12)/4-(-2)

-3/6

=-0.5

y=mx+b

12=-0.5(-2)+b

12=1+b

12-1=b

11=b

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
