Can we get a picture or something?
The points (1, 2) and (4, 2) both have the same y-value, so that is the horizontal line y = 2.
The given point has y-value of 3, so the line passing through it will be
... y = 3
_____
There is no x-term because the slope is 0. We could write it as
... y = 0x +3
but this simplifies to
... y = 3
<span>To regroup 378 x 6, you must first establish the place values of each digit. 3 has a place value of 300, because it is in the hundreds column; 7 has a place value of 70 because it is in the tens column; 8 has a place value of 8 because it is in the units column. This means you can regroup 378 x 6 as (300 x 6) + (70 x 6) + (8 x 6). This makes 2,268. </span>
