y = 1.5x is in the form y = mx + b
so the slope is 1.5, which is the rate of change of y with respect to x
since the graph of y = 1.5 x is a straight line which leans to the right, the y will always be increasing as the x in increasing.
since comparing y = 1.5x to y = mx + b
b = 0 , so the y-intercept is 0
(0,0), (4, 6) . ....
just pick any x and multiply it by 1.5
e.g. x = 4, then y = 1.5(4) = 6 ---->(4,6)
I have a problem with this:
y=1.5x
Questions:
What is the rate of change between the variables?
State whether the y values are increasing or decreasing, or neither, as x increases
Give the y intercept
List the coordinates of two points that lie on the graph of the line in the equation
I just came to the school and the teacher hasn't done anything to help, so I am completely lost. Please help!
