Slope intercept form slope: ⅖ y-intercept: -2

y= ⅖x - 2

Step-by-step explanation:

Formula: y = mx + b (m is the slope and b is the y intercept)

Info given:

m= 2/5

b= -2

Plug the info given into the formula, you get (2/5)x -2

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
