Question

Find the equation of the linear function represented by the table below in slope

intercept form

Answer 1

y=x+2.

Explanation:

1. if the point A has coordinates (-3;1) and B - (1;3), then it is possible to make up the equation:

`(x-X_A)/(X_B-X_A)= (y-Y_A)/(Y_B-Y_A); \ => (x+3)/(4) =(y+1)/(4);`

2. if to evaluate the equation, then

x+3=y+1; ⇔ y=x+2 (slope-interseption form).
