Question

Work out
m
and
c
for the line:
y
=
x
+
4

Answer 1

m = 1

c = 4

Explanation:

First let's review what a slope-intercept form is.

Slope-intercept form is a specific form of linear equations. It always has y on one side and all the other terms on the other. Its structure is:

`y = mx + c`,

where m is the slope and c is the y-intercept.

You can easily read slope (m) and intercept (c) in your equation.

`y = mx + c\\y = x + 4`

You can see that m in front of x is 1, because x = 1x. Multiplying with 1 perserves the number.

So:

`m = 1\\c = 4`
