1. find the coordinate points for x= -3 & x=4, when the linear function y= 4x + 3 is graphed. write answers as points (x, y).

(-3, -9) and (4, 19)

Step-by-step explanation:

When X = -3

Y = 4x + 3

Y = 4(-3) + 3

Y = -12 + 3

Y = -9

When x = 4

Y = 4x + 3

Y = 4(4) + 3

Y = 16 + 3

Y = 19

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

nothing extraneous has been found!

16 is the absolute value
