Question

Work out m and c for the line:

y = 2 − 3 x

Answer 1

Y = mx + c
This is the equation to find linear graphs
You have
Y = 2 - 3x
Rearranged
Y = + 2 - 3x
Y = -3x + 2
So

What do you think m and c are if
Y = mx + c and

Y = -3x + 2

Answer 2

m = -3

c = 2

Explanation:

This equation is given in slope-intercept form. The general structure of these equations is:

y = mx + c

In this form, "m" represents the slope and "c" represents the y-intercept. As you have been given the entire equation, the only thing you have to do is rearrange the equation to find which values correspond with the variables.

y = 2 - 3x -----> y = -3x + 2

Therefore,

m = -3

c = 2
