Question

equation: 2x + 3y = 1,200

Describe how you would graph this line using the slope-intercept method.

Answer 1

@jdoe0001

Answer 2

hmm

Answer 3

slope-intercept formula y = mx + b
rearrange eqn in that format

Answer 4

when x = 0 what is y?
when y = 0 what is x?

Answer 5

I don't get why you're replacing the x and y with 0?

Answer 6

the easiest values to use to get 2 of the points to graph
when x = 0 y = 1200 so you have the point (0, 1200)
when y = 0 find x this is another point on the line
connect the points to get the line satisfying y= -2/3x + 1200

Answer 7

you can use any x values to calculate the corresponding y value and then get points on the line to graph

Answer 8

recall the 400 was the y-intercept, thus is where the line touches the y-axis, or INTERCEPTS it thus the point (0, 400)

Answer 9

if the slope is positive
the graph goes UP from left to right

if it's negative
the graph goes DOWN from left to right

lemme recorrect my correction darn =)

Answer 10

so
y=(0,400)
and x is ???????????
sorry im just confused on what is plotted on the x axis.

Answer 11

hold... on I got a few things mixed up

Answer 12

correction the intercept is 1200/3 = 400
the point is (0, 400)

Answer 13

@MonikaCristello do you have any questions about the method?
