The point-slope form:

We have the points (1, 2) and (3, 6). Substitute:

Find the b value by plugging in the slope and known coordinates,
-2=0(4)+b
-2= 0+b
-2=b
You can also tell this without calculating since a slope of 0 will always have the same y value. Therefore if (4,-2) is on the line, the y value of the whole line must be -2.
Final answer: y=0x-2, which is y=-2
Answer:
a
Step-by-step explanation:
-12y+14-9y=14
-21y=0
y=0, x=7
X+2 is the correct answer
