Answer:
y = x +
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 10x + 1 ← is in slope- intercept form
with slope m = - 10
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, thus
y = x + c ← is the partial equation
To find c substitute (5, 7) into the partial equation
7 = + c ⇒ c = 7 -
=
y = x +
← equation of line
I know 
as a decimal is 0.7777778 and I know 
as a decimal is 0.88889. Which one is bigger? 0.7778 or 0.8889. 0.8889 is bigger so your answer is 7/9<8/9
