Given two points find the equation of the line using point slope

The video tutorial explains how to find the equation of a line given two points using the slope-intercept form. It begins by introducing the slope-intercept form, Y = MX + B, where M is the slope and B is the Y-intercept. The tutorial then demonstrates how to calculate the slope using the slope formula and distinguish between the X and Y coordinates. After finding the slope, it shows how to determine the Y-intercept by plugging in one of the points into the equation. Finally, the tutorial concludes by forming the complete equation of the line.

What is the general form of the slope-intercept equation?

• B = YX + M

• X = MY + B

• Y = B + MX

• Y = MX + B

How do you label the coordinates when calculating the slope?

• M1, M2, N1, N2

• A1, A2, B1, B2

• X1, X2, Y1, Y2

• P1, P2, Q1, Q2

What is the result of subtracting a negative number from another negative number?

• Zero

• An undefined number

• A positive number

• A negative number

Which point can be used to find the Y-intercept in the slope-intercept form?

• Neither point

• Any point on the line

• Only the first point

• Only the second point

What is the Y-intercept if the equation is Y = -1/2X + B and B is found to be 1/2?

• 2

• 1/2

• -1/2

• 0
