Question

Find the equation of the line below. Arrange your answer in the form y = mx + b, where b is the constant.

Answer 1

you see from the graph that x increases by 4, y decreases by 3, right?

Answer 2

@Annа ?

Answer 3

yup @lucaz

Answer 4

so, this is how you find the slope when you have a graph

Answer 5

slope m = -3/4

Answer 6

thats no right, ive tried that @lucaz

Answer 7

-3/4 is not correct?

Answer 8

yes

Answer 9

how come? you can also try the formula
\[\large m=\frac{y-y_1}{x-x_1}\]

Answer 10

i got it. its -3x/4 +3

Answer 11

yeah, -3/4 is the slope as I said..

Answer 12

and the y intercept is 3, you got it right
