Question

Is this correct? slope intercept form

Answer 1

answer:

m = (7 - 12)/(-2 - 3)
m = -5/-5
m = 1
y = mx + b
12 = 1(3) + b
12 = 3 + b
12 - 3 = 3 + b - 3
9 = b
b = 9

y = mx + b
y = 1x + 9
y = x + 9

Answer 2

Let's check your answer. We do this by plugging in each ordered pair in for x and y


(-2,7) means x = -2 and y = 7
y = x + 9
7 = -2 + 9
7 = 7 ... works


(3,12) means x = 3 and y = 12
y = x + 9
12 = 3 + 9
12 = 12 ... works


so the answer is confirmed

Answer 4

The solution set -----> { ( -2, 7 ) , ( 3 , 12 ) , ... etc }

of a linear equation in two variables -----> y = x + 9

is the set of all ordered pairs of numbers -----> { ( -2, 7 ) , ( 3 , 12 ) , ... etc }

that make the equation into a true statement ------> 7 = 7 , 12 = 12 , ... etc.
