Understanding Linear Equations from Two Points

What is the general form of a linear equation in slope-intercept form?

• y = ax^2 + bx + c

• y = mx + b

• y = a/x + b

• y = mx^2 + b

How do you label the coordinates of the given points when calculating the slope?

• P1, Q1 and P2, Q2

• X1, Y1 and X2, Y2

• M1, N1 and M2, N2

• A1, B1 and A2, B2

What is the slope of a line if the given points are (-6, 7) and (9, 8)?

• 1/3

• -1/3

• 3

• -3

Which point is used to find the y-intercept in the equation y = mx + b?

• Any of the given points

• Only the first point

• Only the second point

• Neither of the points

What is the final equation of the line with points (-6, 7) and (9, 8)?

• y = 1/3x + 5

• y = 1/3x - 5

• y = -1/3x + 5

• y = -1/3x - 5
