1-5. Graph MU (line MU) for M(-1, 1). (Look at the bottom of the pic)

a) The slope of the line MU is

b) The distance between the coordinates of the line MU is √41

c) There are differences and similarities between (a) and (b).

The slope of a line is used to describe how steep the line is. This is expressed mathematically as;

where:

(x1, y1) and (x2, y2 are the coordinate points)

From the graph shown, we are given the coordinates M(-1, 1) and U(4, 5)

a) The slope of the line MU will be expressed as;

The slope of the line MU is

The formula for calculating the equation of a line is expressed as y = mx + b

b is the y-intercept.

Substitute m = 4/5 and (-1, 1) into the expression y = mx + b

Get the required equation.

Substitute m = 4/5 and b = 9/5 into y = mx + b

The required equation of the line is 5y - 4x = 9

b) The formula for calculating the distance between two points is expressed as;

Substitute the given coordinates in (a) to get the distance MU

Hence the distance MU is √41

c) There are similarities and differences in the calculations in (a) and (b). The similarities lie in the usage of the change in the coordinates for the calculation of the slope and the distance.

The difference is that we do not need the slope of the line to calculate the distance MU but the slope y-intercept is required to calculate the equation of the line.
