Front

What is the equation of a line that passes through the point (-1, 2)?

Back

The equation can be in the form y = mx + b, where m is the slope and b is the y-intercept. However, if the line is vertical, it can be represented as x = -1.

Front

What is the solution to the equation 2x + 5 = 8x?

Back

The solution is x = 10/6 = 5/3.

Front

How do you calculate the probability of selecting a male from a group of 4 males and 8 females?

Back

Probability = (Number of males) / (Total number of individuals) = 4 / (4 + 8) = 1/3.
