Answer:
y = 2x + 3
Step-by-step explanation:
The equation of a straight line graph is y=mx+c
m is the gradient of the line. You can work this out like this:
Change in y ÷ change in x
So you have your 2 coordinates, (1,5) and (0,3).
(be careful to choose one coordinate to go first and one to go last)
So to work out m, you would do
5-3 ÷ 1-0 = 2/1 = 2
so that is the first half of the equation, y = 2x
but now you need c, which is the y-intercept. So this is the point on your graph where the point crosses y, so in your question, it would be 3 because it crosses y at 3.
So your answer is y = 2x + 3
