Indicate in standard form the equation of the line passing through the given point and having the given slope
Naddik [55]
ANSWER


The equation is

y - 5x + 20 = 0


EXPLANATION

Let the equation be
y = mx + c

where
m = 5
is the slope of the line.


We substitute this value to obtain,

y = 5x + c


Since the line passes through
(4,0)
we can use this point to determine the value of c.



We substitute this point to obtain,

0 = 5(4) + c


0 = 20 + c


c =  - 20


Our equation now becomes

y = 5x - 20


We can write this in standard form as


y - 5x + 20 = 0
