Answer:
y=4x-8 meets the x axis at point A
, In other words Point A intersects the x axis, (Draw the graph and you will find that A=2) or simply solve for it setting y=0
4x-8=0
4x=8
x=2(Intersection)
Second part of the question find the equation of the line with gradient 3 that passes through point A,
Gradient is slope.
y=mx+c
m is the slope
In this equation it is 4x (Slope is 4)
So you want a line that intersect the x axis at the same point (A) at 2. but with slope=3
simply,
y=3x-6
