Hi,
Using the point-slope formula,to determine slope of L1
Points are (-4,0) and (0,6)which are the x and y intercepts
m = 6-0 / 0-(-4) = 6/4 = 3/2
the standard slope-intercept form for an equation of a line is: y = mx + b
where m is the slope and b the y-intercept. Equation of L1 is y = (3/2)x + 6
Line2 parellel to L1 also has slope of 3/2
y = 3/2x + b L2 is to pass thru Pt(0,0) so b = 0
Equation of L2 is y = (3/2)x
