Use the points (1998,13.60) and (2003,19.00) to write the slope-intercept form an equation for the line of fit shown in the scatter plot

Slope: 1.08

y-intercept: -2144.24

Step-by-step explanation:

Equation of a Line

Given two points (a,b) and (c,d), we can write the equation of the line passing through both points in the form

\displaystyle y-b=\frac{d-b}{c-a}(x-a)

We have the points (1998,13.60) , (2003,19.00), plugging them into the formula:

Operating

Slope: 1.08

y-intercept: -2144.24

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
