Answer:
Frankly, substitution is almost always a better method. Graphing is a very precise and time consuming process where you have to calculate several..
Answer: y=2x+8
Step-by-step explanation:
(2,12)=(x1,y1)
(-7,-6)=(x2,y2)
(y2-y1)/(x2-x1)=(-6-12)/(-7-2)=-18/-9=2=m
y=mx+b
y=2x+b
insert (2,12) to y=2x+b
12=2*2+b
12=4+b
8=b
y=2x+8
Answer:
3 1/6. Hope this helps :)
The "rule" being described here is nothing more than the input/output of a mathematical function.
<span>For every input 'x' value supplied, you only need to subtract three to it. For every input 'y' value, you only need to add four to it. </span>
<span>Example: I'll use variable 'm' to represent this function. Variable 'p' will represent the current input point. </span>
<span>m(p) = p[x - 3, y + 4] = p[-7 - 3, 0 + 4] = p[-10, 4]. 'p[]" is just the point.</span>
