Find the equation of a line whose slope is 4 and which passes through

1.	Find the equation of a line whose slope is 4 and which passes through the point (5, - 7)
Answer» As slope is given m = 4 and passing through (5, - 7).using slope - intercept form of equation of line, we will find value of intercept first y = mx + c ………..(1) - 7 = 4(5) + c - 7 = 20 + c c = - 7 - 20 c = - 27 Putting the value of c in equation (1), we have y = 4x + ( - 27) y = 4x - 27 4x - y - 27 = 0 So, the required equation of line is 4x - y - 27 = 0.

Find the equation of a line whose slope is 4 and which passes through the point (5, - 7)

Answer»

As slope is given m = 4 and passing through (5, - 7).using slope - intercept form of equation of line, we will find value of intercept first

y = mx + c ………..(1)

- 7 = 4(5) + c

- 7 = 20 + c

c = - 7 - 20

c = - 27

Putting the value of c in equation (1), we have

y = 4x + ( - 27)

y = 4x - 27

4x - y - 27 = 0

So, the required equation of line is 4x - y - 27 = 0.
