(4,7)(0, how the y values are the means that the line is horizontal line with a 0 slope and is represented by y = a number. that number is the number in the y ur equation is y = y = 0x + the slope, in y = mx + b form, is in the m position.

y = 0x + we need it in standard form : ax + by = c
0x + y = 7 < == standard form
