Answer:
2.4
Step-by-step explanation:
We divide 0.5 by 3 giving us approximatly 0.16, we have found the rate of change. Now we multiply 15 by 0.16 equals 2.4.
I believe it has infinite solutions? Not sure
You can graph this via graphing calculator and see that the lines intersect almost infinitely.
The point slope form of a line is written as y - y1 = m(x -x1)
Where m is the slope and x1 and y1 are the points on the line.
You are told the slope is 3 and the point is (2,-1/2)
x1 is 2 and y1 is -1/2
Replace those in the equation to get:
y- (-1/2) = 3(x-2)
Simplify to get the final answer:
y + 1/2 = 3(x-2)
34/85%=34/0.85=40
So that's your answer.
