Answer:
[tex]y=-\frac{9}{8}x+7[/tex]
Step-by-step explanation:
we know that
The equation of the line into slope intercept form is equal to
[tex]y=mx+b[/tex]
where
m is the slope
b is the y-coordinate of the y-intercept
In this problem we have
[tex]b=7[/tex] ------> because the point [tex](0,7)[/tex] is the y-intercept
point [tex](8,-2)[/tex]
substitute the value of x , y and b in the equation to solve for m
[tex]y=mx+b[/tex]------> [tex]-2=m(8)+7[/tex]
[tex]m(8)=-2-7[/tex]
[tex]m=-9/8[/tex]
therefore
the equation is equal to
[tex]y=-\frac{9}{8}x+7[/tex]
