If y varies directly as x, and y = 64 when x = 8. Find y when x = 12

1 answer:

7 0

Use the proportion 8/64 = 12/y. Cross multiply to get 8y = 768. Divide both sides by 8 to get y=96

Answer:

Step-by-step explanation:

If you convert the first equation to y=mx+b form, it will be the same as the second equation.

6x - 15y = 15

-15y = -6x + 15

y = $\frac{2}{5}$ x -1

Because the 2 equations are the same now, they are the same line.

5-7 = -2 and 1-6= -5 so the slope would be 2/5. you would set it up like this:

y=2/5x and then your y-intercept

Answer:

3/4 or .75

Step-by-step explanation:

slope = dy/dx

dy = 1 - -2 = 3

dx = 2 - -2 = 4

slope = 3/4
