<h2>Answer with explanation:</h2>
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.
- Here m=1.2 and c=0
<em>i.e. the slope represents the stride rate of Alberto i.e. the rate at which he is walking.</em>
- and the y-intercept represents the speed of Alberto when he took 0 steps i.e when x=0.
<em>It represents that his speed is 0 meter per minutes when he did not took any step.</em>

The slope intercept form of the line whose points are (1,5) and (-2,-4) is y=3x+2.
Given two points of a line (1,5) and (-2,-4).
We have to form an equation in slop intercept form.
Equation is relationship between two or more variables which are expressed in equal to form.Equations of two variables looks like ax+by=c.
Point slope form of an equation is y=x+mc where m is slope of the line.
From two points the formula of equation is as under:
(y-)=
*(x-
)
where are the points.
Putting the values of =1,
=-2,
=5 and
=-4.
y-5=(-4-5/-2-1)*(x-1)
y-5=-9/-3*(x-1)
y-5=3(x-1)
y-5=3x-3
y=3x-3+5
y=3x+2
Hence the slope intercept form of the line having points (1,5)(-2,-4) is y=3x+2.
