Equations of Lines

Question 1

what does each of these mean.. y=mx+c

Answer 1

y- y co ordinate
m- gradient
x- x co-ordinate
c- y intercept

Question 2

what to remember when writing the c/ y intercept?

Answer 2

ALWAYS WRITE IT AS A CO ORIDNATE.. example (0,5)

Question 3

how would you plot this question on a graph.. y= 2x-5

Answer 3

first start by finding the gradient (m) which is 2

then find the y intercept (c) which is (0, -5).

then plot (0, -5) on the graph and then to plot three other point by going one across and two up.
