Hello!

The chance of getting a football card is 7 / 10
The chance of then getting a basketball card is 3 / 10

Multiply these two numbers

7/10 * 3 / 10 = 21/100

21/100 = 0.21

The answer is 0.21 or 21%

Hope this helps!

Write the point-slope form of the equation of the line passing through the points (-5, 6) and (0, 1).
Y_Kistochka [10]
The point slope form:
y - y_1 = m(x - x_1)

We need to find the slope. To find the slope we can use the following formula:
\frac{y_2 - y_1}{x_2 - X_1}

Use the points <span>(-5, 6) and (0, 1) and plug it into our slope formula and solve:
</span>\frac{1 - 6}{0 - (-5)}
\frac{-5}{5} = -1

So our slope is -1 which means m = slope = -1 
Now that we have our slope lets create the point slope form

Our point slope form equation is y - y_1 = m(x - x_1) Remember 
m = slope = -1. Also, we are going to use the point (-5,6).

First insert the m = slope = -1 number where m is located
y - y_1 = -1(x - x_1)

Next, insert the -5 from (-5,6) where x_1 is located and the 6 from (-5,6) where y_1 is located.
y - y_1 = -1(x - x_1)
y - 6 = -1(x - (-5))
Now simplify 
y - 6 = -1(x - (-5))
y - 6 = -1(x +5) <-------Answer
