Write an equation of a line that is parallel to y=-3x+5 that passes through the point (0,-4)
elena55 [62]

Answer:

{ \rm{y =  - 3x + 5}}

Gradient = -3

• Parallel lines have the same gradient, therefore gradient, m is -3

{ \rm{y = mx + c}}

• At point (0, -4)

{ \rm{ - 4 = ( - 3 \times 0) + c}} \\  \\ { \rm{c =  - 4}}

y intercept is -4

{ \boxed{ \boxed{ \mathfrak{answer : }}{ \rm{\:  \: y =  - 3x - 4}}}}
