Question 29125: Find the slope and the y-intercept.
y = 7x

You can put this solution on YOUR website! Find the slope and the y-intercept.
y = 7x
The slope and the y-intercept form of equation to a straight line is
y = (m)x +(b) ----(*)
The given line is
y=7x which can be written as
y =(7)x +(0) ----(1)
Comparing our line with (*),we have
slope = 7 and y-intercept = 0
Note: Observe the equation of the given line.
There is no free constant in the equation.
There is only the x-term and the y-term
This means O(0,0) namely the origin is a point on the line
Any line of the form y=mx or equivalently Ax+By=0 represents a line through the origin and hence has no x-intercept and has no y-intercept. That is to say a line through the origin has x-intercept = 0 and y-intercept = 0
