Question

Write an equation for a line through (-2,4) with m= -4 in standard form.

A)4x + y = - 4
B)4x - y = - 4
C)-4x - y = 4
D)-4x + y = - 4

Answer 1

4x+y=-4

Explanation:

gradient(m)=y2-y1/x2-x1

the line also passes through points (x,y) and (-2,4)

-4=4-y/-2-x

cross multiplying

8+4x=4-y

option(A):4x+y=-4

is your answer.
