Answer:
Step-by-step explanation:
I'm going to assume you mean passes through the point (-2,5) since -2 and 5 could mean a lot of different things
To find the perpendicular line's gradient, you would know that m1*m2 = -1
In this case m1 = 7, so m2 must be -1/7
Now we substitute the gradient into the equation
y = -1/7x + b
To find b, we substitute (-2,5) into the equation above
5 = -1/7*-2+b
5 = 2/7 + b
b = 33/7
Therefore the equation of the line is
y = -1/7x+33/7
1 times fee doesn't change
150 doesn't change
thtat is the 1 times fe
service fee per month
55 times x=other part
x=number of months
55x=monthly fee part
y=total cost
Answer:
Step-by-step explanation:
Slope-intercept form of an equation is written as 
, where 
is the slope and 
is the y-intercept.
The slope of a line that passes through the points 
and 
is 
. Using the coordinates 
and 
as given in the problem, we have slope of this line to be:
.
Now using this slope we've found and any point the line passes through, we can find the y-intercept of this equation:
Therefore, the equation of this line in slope-intercept form is 
.
