(0, 4)
(1, 7)
y = 3x + b
(4) = 3(0) + b
b = 4
y = 3x + 4
Rate of change: 3 initial value: 4
2.)
(0, -5)
(1, -3)
y = 2x + b

Step-by-step explanation:
you want to solve it out
start with multiplying z to each. you don't multiply it to the 6 because it is in the same parenthesis set, but you multiply it to everything in the other set. After multiplying, you get: ,
,
now do that to the 6. After multiplying you get: ,
,
now set it all next to each other +
+
+
+
+

work combining the squares:
work combing the single z's:
to get this: +
