Answer 1

\[m=5\]

Answer 2

use formula :
y = mx + c ; with m=slope

Answer 3

y = 5x where can you get c?

Answer 4

@Buensalida It is better if you go through the chapter, "Equation of a straight line".
Guide: Now substitute the given points (-4,1) in the equation. You will get c.

Answer 5

it should be
y = 5x + c, now to find value of c subtititue point (-4,1) to that equation

Answer 6

subtitute*

Answer 7

1 = 5(-4) + c

Answer 8

now simplifying you get, 1 = - 20 + c
i.e. c = 21.
Now substitute this to equation y = 5 x + c.

Answer 9

y = 5x + 21

Answer 10

you are right
