has a lope of -5 and passes through (3,4)

Sagot :

so i assume the question here is to find the equation of the line.

1st step is to use the equation of a line y=mx + b where m is the slope and substitute the value of given x and y to find the y-intercept b

substitute given values to the equation

4 = (-5)(3) + b

4 = -15 + b

4 + 15 = b

b = 19

now substitute the value of b and m to the equation

y = -5x + 19 (rearrange to standard form)

5x + y = 19 -------this is the answer
