The linear function y = 1.2x represents alberto’s speed, y, in meters per minute, when his stride rate is x steps per minute.

explain what the slope and y-intercept of the linear model represent in the context of the situation.

The linear function is given by:

where y represents Alberto's speed in meters per minutes.

when his stride rate is x steps per minute.

We know that for any linear function of the type:

m represents the slope and c represents the y-intercept of the function.

i.e. the slope represents the stride rate of Alberto i.e. the rate at which he is walking.

It represents that his speed is 0 meter per minutes when he did not took any step.

noncoplanar points are points that do not lie on the same line.
