Understanding Linear Equations

The video tutorial explains how to find the equation of a line that passes through a given point with a specific slope. It introduces the formula Y = MX + b, identifies the slope and coordinates, and demonstrates how to substitute these values into the formula to solve for the y-intercept, B.

What is the slope of the line that passes through the point (-2, -8)?

• 1

• 2

• 3

• 4

Which formula is used to find the equation of a line?

• Y = X + b

• Y = MX + b

• Y = M + b

• Y = MX

If the slope (M) is 3 and the X value is -2, what is the Y value?

• -2

• -6

• -4

• -8

What is the value of the y-intercept (b) when the line passes through (-2, -8) with a slope of 3?

• -2

• -8

• -4

• -6

How do you solve for the y-intercept (b) in the equation Y = MX + b?

• By using a calculator

• By substituting known values of X, Y, and M

• By drawing a graph

• By guessing
