y = mx + b is standard form where m = slope and b = y intercept y = 7x + 3 b = 3 = y intercept
7 and the y intercept is 8/3
7y+3x-21 =0 7y = -3x+21 y = -3/7x+3 The y intercept is 3
The answer to the math problem -3 7x plus 7 is x equals 1/3.
Hey there - First you must put this in y = mx + b (slope intercept format) format, and it will make finding the answers easy. 7x + 3y = -9 3y = -7x - 9 y = -7/3x - 3 Your slope is m, or -7/3 your y intercept is b, or -3 cheers! Donny
