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+=+%28y2-y1%29%2F+%28x2-x1%29
step 1 - find the slope. Substitute our coordinates in for x's and y's to get
m+=+%28-4-%28-4%29%29%2F+%285-0%29
which is
m+=+%280%29%2F+%285%29 = 0
step 2 - put slope information and a point into
y+=+mx+%2B+b
We get
-4+=+0%2A0+%2B+b
b+=+-4
step 3 - write the final equation as
Y+=+0x+-+4
or
y+=+-4
