Let
A(4,0)
B(12,5)
C(20,10)
we know that
The x-intercept of the line is the value of x when the value of y is equal to zero
The y-intercept of the line is the value of y when the value of x is equal to zero
The point A(4,0) is the x-intercept of the line
<u>Find the slope AB</u>
m=(y2-y1)/(x2-x1)
mAB=(5-0)/(12-4)--------> mAB=5/8
<u>with the slope m and the point A(4,0) find the equation of the line</u>
y-y1=m*(x-x1)----------> y-0=(5/8)*(x-4)-------> y=(5/8)x-2.5-----> y=0.625x-2.5
<u>Find the y-intercept</u>
For x=0
y=0.625*0-2.5---------> y=-2.5
the y-intercept is the point (0,-2.5)
therefore
<u>the answer is</u>
the x-intercept is the point (4,0)
the y-intercept is the point (0,-2.5)

Step-by-step explanation:
We have been given that Jeanie stated that the equation of this line best fit for the scatter plot is
.
Let us find the slope of the line of best fit using points (2,7) and (4,6) in slope formula.


We can see that slope of line of best fit is
.
Since the equation of a line written in slope-intercept is in form:
, where m=slope of line, b= y-intercept.
Upon substituting m=
and coordinates of one point in slope-intercept form of equation we will get,



Upon substituting m=
and b=8 in slope intercept form, we will get,

We can see that equation of the line of best fit is
. Jeanie got 1/2 as slope of the line of best fit, which is wrong, therefore, Jeanie's equation of the line of best fit is not correct.
