Question

Which equation best represents the line?

y = 3 over 4. x + 4
y = 4 over 3.x + 4
y = 4x + 3 over 4.
y = 4x + 4 over 3.

Answer 1

the last two are out becuase the y intercept is 4 right?

Answer 2

yes

Answer 3

okay now the slope of the line is the measurement of the change in y over the change in x so for instance if the slope was 1/2 than you would start on one point and move 1 up and 2 across.

Answer 4

you could also use the formula i gave you last time

Answer 5

what do you wanna do?

Answer 6

I got 0,2

Answer 7

did you use the formula?

Answer 8

x1-y1 AND x2-y2 right

Answer 9

normally when you use the formula you'll get a fraction becuase it uses those two points in the equation

Answer 10

I'll do it a second time

Answer 11

if you use the y intercept as 0, 4 that can be one of your points then just find another point on the graph like 4, 7

Answer 12

I got 3/4

Answer 13

yep thats right :) good job

Answer 14

so A or C would be a answer

Answer 15

its only one of them. remember that a lines equation is y = (slope)x + (y intercept)

Answer 16

c

Answer 17

not really. Whats the y intercept do you remember?

Answer 18

3/4

Answer 19

thats the slope

the y intercept is where the line intersects with the y axis

Answer 20

the first thing we did was find the y intercept do you remmebr what it was?
