Write an equation in point-slope form for the line through the given point with the given slope.

(9, –1); m = 4/3

y – 9 = 4/3(x + 1)

y – 1 = 4/3(x + 9)

y – 1 = 4/3(x – 9)

y + 1 = 4/3(x – 9)

On a piece of paper graph f(x)=5•(0.4)^x

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.
