(1). What happens to the graph of y = 8x when you change it to y = 2(8x)? (2). Explain what happens to the graph of y = 4x if you change it to y = 4x + 2.
first off do you understand slope intercept form?
no
slope intercept form is y= m x + b m = slope x = x intercept b = y intercept
this is where the coordinate plane is used do you understand that there is an x axis y axis on the coordinate plane?
|dw:1354518063143:dw| does this come to mind?
yes.. a little..
|dw:1354518295750:dw| you want to get the slope of the line b = is the y intercept ( where you begin you line from) IF THERE IS NO Y INTERCEPT DISREGARD "B" example: y = 3x + 2 , 2 is y intercept y = 3x + 2 , no y intercept y = mx + b you want to find slope of the line m = slope solve for m y m = --- x plug in values
can you please just show me
Do you still need help?
as a fraction 8 is 8 --- 1 (change of y ) (rise) 8 ------------ = ------ ----- (change of x) (run) 1 |dw:1354520300613:dw| the graph is not to scale it is for you to get the point
there is still more work to this problem but thats how you graph
