y = k * x
When x = 7 then y = - 58
- 58 = k * 7 Divide both sides with 7
- 58 / 7 = k
k = - 58 / 7
y = k * x
when x = 6
y = - 58 * 6 / 7
x = - 348 / 7
Suppose that y is directly proportional to x.
a. Use the given information to find the constant of proportionality k.
b. Then use y=kx to find y for x=6
y=-58 when x=7
