Question

Write the equation of a line that passes through the point (-1,-2) and has a slope of -4

Answer 1

Y=2x+2

Explanation:

The slope-intercept equation of a line :

y = m x + c

Here

m = slope c = y

-intercept

Therefore, the required equation is:

y = 2 xc

Putting the point

( 1 , 4 )

in it as it lies on line, we get:

4 = 2 + c

Therefore

c = 2

So

y = 2 x + 2

is the required equation.
