Answer:
28x-35
Step-by-step explanation:
4x*7=28x
5*7=35
The equation of the line is y - 3 = 5(x - 8) ⇒ c
Step-by-step explanation:
The point-slope form of the linear equation is
, where:
- m is the slope of the line
is a point on the line
∵ The line passes through point (8 , 3)
∴
= 8 and
= 3
∵ The slope of the line is 5
∴ m = 5
- Substitute these values in the form of the equation below
∵ 
∴ y - 3 = 5(x - 8)
The equation of the line is y - 3 = 5(x - 8)
