Two different linear functions are shown below with two points given from each function. use slope-intercept form or point-slope form to find the equation of each. linear function a points: (–5, –2), (–5, 7) linear function b points: (7, –5), (–2, –5) function a has: the equation of line a is: function b has: the equation of line b is:

The slope-intercept form of a linear function is .

Linear function A

The points are given as: (-5, -2) and (-5,7)

First, we calculate the slope (m) of the line

So, we have:

The slope implies that, the point is a vertical line that passes through

So, the equation is:

Linear function B

The points are given as: (7,-5) and (-2,-5)

First, we calculate the slope (m) of the line

So, we have:

The slope implies that, the point is a horizontal line that passes through

So, the equation is:

See attachment for the graph of both functions.

Step-by-step explanation:

Function A:

(-5, -2), (-5, 7) It's not a function, because for x = -5 we have two different values of y!

The graph is a vertical line x = -5

Function B:

(7, -5), (-2, -5) It's a function.

The graph is a horizontal line y = -5
