Answer:
Step-by-step explanation:
Slope-Intercept form is y=mx+b
m is the slope and b is the y-intercept
You can use any ordered pairs but I suggest ones that touch down on an intersect like (0,70) and (3,60)
slope=[tex]\frac{y^{2} -y^{1} }{x^{2} -x^{1} }[/tex]
slope using (0,70) and (3,60)=[tex]-\frac{10}{3}[/tex]
The y-intercept is 60 since its the number that touches the y-axis
So the equation for the trend line is
[tex]y=-\frac{10}{3} x+70[/tex]
