Question 254672
The question was:
write an equation of the line that passes through each pair of point (0,-4),(5,-4). I think you want 1 line going through both points. We need the slope formula which is
{{{m = (y2-y1)/ (x2-x1)}}}
step 1 - find the slope. Substitute our coordinates in for x's and y's to get
{{{m = (-4-(-4))/ (5-0)}}}
which is
{{{m = (0)/ (5)}}} = 0
step 2 - put slope information and a point into
{{{y = mx + b}}}
We get
{{{-4 = 0*0 + b}}}
{{{b = -4}}}
step 3 - write the final equation as
{{{Y = 0x - 4}}}
or
{{{y = -4}}}
