Answer:
the constant of proportionality is the ratio between two directly proportional quantities.
b. k=y/x or y = k*1/x
The answer is C. The formula for point slope for is y- y1 = m(x - x1). y-(-2) = 1/2(x-(-3). This is rewritten as y + 2 = 1/2(x + 3)
A and F are true. because A is y=2x+7, and F is y=2x+7.
We know that the equation y=2x+7 has a point 0,7 and with the slope being 2, rise over run would make another point 1,9. And because these are linear equations if the equation y=2x+7 goes through 1,9 then it will go though -2,3 as well.
