Answer:
y = 9x + 9
Step-by-step explanation:
so the points are:
(0,9) (1, 18) (2, 27) (3, 36) (4, 45)
since the y intercept is when x is 0 write it in the equation!
y = mx + 9
now to solve for slope
use the equation y2 - y1/ x2 - x1 or y1 - y2/x1 - x2
sooo use (1, 18) and (2, 27)
27 - 18/2 - 1
9 / 1 = 9
y = 9x + 9
check with the points you did not use!
(3, 36)
36 = 9(3) + 9 ?
36 = 27 + 9?
36 = 36
