When Serena is 10, her mom is 3*10=30. Her mom is 20 years older than Serena.

If her mom's age divided by half is equal to Serena's, then she will be twice as old as Serena.

20 + 20 = 40
20 * 2 = 40

Serena will be 20, her mom will be 40.

What equation of a line that passes through (7, 8) and has a slope of -3?
IgorC [24]

Answer:

The equation of this line is y = -3x + 29

Step-by-step explanation:

In order to find this, start with the basic form of point-slope form.

y - y1 = m(x - x1)

Now put the slope in for m and the point in for (x1, y1)

y - 8 = -3(x - 7)

Now solve the equation for y.

y - 8 = -3x + 21

y = -3x + 29
