Question

Give the slope and y intercept of each line and graph it.
y=3x-1
slope: 3
y: -1
But how would I go about getting the points for graphing?

Answer 1

a simple solution for any type of graph is is to choose a number for x and solve for y
for example if x = 0 then y=3(0)-1 which is -1
so x one set of points is x=1,y=-1

Answer 2

i mean x=0 y=-1

Answer 3

?

Answer 4

you can substitute any number for x and figure out what y is.
if Y=3x-1 you can pick any number for x and solve for y.
for example if you pick 1 for x you are left with the equation y=3(1)-1
notice I put 1 in the place of x
then you use algebra to solve for Y .
y=3(1)-1
y=2
then the point on the graph is the value you picked for x which is 1 and the solution for y which is 2
the set of points is (1,2)
