How does y=mx+c work

Answers

Ok so, y = mx + c is the equation of a line
When a graph is written in this form, m is the slope/gradient and c is the y - intercept.
This form is needed when a question asks for the equation.
Lets say they give 2 sets of coordinates, we can use the point slope formula to find the slope (m)

point slope formula:
(y₂ - y₁) = m(x₂ - x₁)

Then we substitute any of the two set of coordinates to find c, the y - intercept. 

So the line has a gradient of m and y - intercept of c

Please help don't understand What are the domain and range of the function {(5, 3), (7, 1), (11, –2), (4, 9), (–2, 4)}?

A.
Domain: {3, 1, 9, 4}; Range: {5, 7, 11, 4, }

B.
Domain: {3, 1, –2, 9, 4}; Range: {5, 7, 11, 4, –2}

C.
Domain: {5, 7, 11, 4, }; Range: {3, 1, 9, 4}

D.
Domain: {5, 7, 11, 4, –2}; Range: {3, 1, –2, 9, 4}

Answers

domain is the inputs
range is outputs from inuting inputs

normally domain=x
range=y
(x,y)
domain is all first number
range is all second numbers

we have
(5, 3), (7, 1), (11, –2), (4, 9), (–2, 4)
remember to ignore repeats
Domain: {-2,4,5,7,11}
Range: {-2,1,3,4,9}
