State whether the line through points has a slope of zero or undefined. Also state whether it is horizontal or verticalline

Missing part of question

(a) (-3, 4) and (5, 4)

(b) (4, 5) and (4, -3).

(a) (-3, 4) and (5, 4)

Zero slope

Horizontal line

(b) (4, 5) and (4, -3).

Undefined slope

Vertical line

Step-by-step explanation:

Solving (a): (-3, 4) and (5, 4)

Slope (m) is calculated as:

This gives

This line has a slope of zero.

When slope equals 0, then the line is horizontal

Solving (b): (4, 5) and (4, -3)

Slope (m) is calculated as:

This gives

m = undefined

This line has an undefined slope.

When the slope of a line is undefined, then the line is vertical

the answer is 31.27mph
