Question 274865
The equation of a line L1 is y=.5x
(a) on graph paper draw and label L1
{{{ graph( 300, 200, -4, 5, -10, 10, .5x) }}}
:
The line L2 has the same slope as L1, but crosses the y-axis at 3
{{{ graph( 300, 200, -4, 5, -10, 10, .5x+3) }}}
;
(b) What is the geometric relationship between L1 and L2?
{{{ graph( 300, 200, -4, 5, -10, 10, .5x, .5x+3) }}}
Note that the lines are parallel (parallel lines always have the same slope)
:
(c)write down the equation of L2
y = .5x + 3
(d) on the same grid as part (a) draw the line L2
we did that in b
