Step-by-step explanation:
y = ax + b => ax +b = y
-5= a.1+ b => a + b = -5
-9= a.2+b => 2a+b = -9
________-
-a = 4
=> a = -4
a+b=-5 => b = -5 -a
b = -5+4 = -1
so, the Equation : y = -4x -1
I'm on this question too and all I know is store C is a better buy. I'm not very sure why but I'm pretty sure it is.
Answer:
The equation of line is
Step-by-step explanation:
Here, the two point line are given as is A(5,2) and B(-1,-6)
The slope of the line AB =
⇒ the slope of AB is m = (4/3)
By POINT SLOPE FORMULA:
The equation of a line with slope m and a point (x0, y0) is given as
(y-y0)= m (x-x0)
⇒ The equation of line with point (5,2) is:
Hence, the equation of line is
