Question

Whats an equation i can use to graph coordinates.
problem is y = x - 1

Answer 1

make table of values

Answer 2

find the y-intercept and then graph that along w/ some other values that you found using the slope

Answer 3

and how do i do that? i lost my notes so i dont know the equation to find them

Answer 4

You should find x and y intercepts.
x intercept is when y=0. So, x =1.
y intercept is when x=0. So, y = -1.

Now, draw line through two points (1,0) and (0,-1).

Answer 5

how does x = 1 when there is no value to put in for x and y

Answer 6

because of the way the equation is set up, the x and y intercepts will both have zero in them

Answer 7

y = x -1 (when y = 0, you get 0 = x - 1, which means x = 1).

Answer 8

y = x - 1 (when x = 0, you get y = 0 -1, which means y = -1).

Answer 9

how do you know y is 0

Answer 10

To draw a line, you just need two points. The two easiest points are the "intercepts".
y is zero for the x intercept (where the line intersects x-axis).
x is zero for the y intercept (where the line intersects y-axis).

Answer 11

You don't know y is zero. You are forcing it to zero by focusing on the x-intercept.
