Point slope form for (2,9) as the point and -3 as the slope

y - 9 = - 3(x - 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 3 and (a, b) = (2, 9), thus

y - 9 = - 3(x - 2) ← in point- slope form

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
