In y = mx + b form, the slope is in the m position and the y intercept is in the b position.
5x + 2y = 8
2y = -5x + 8
y = -5/2x + 8.....slope (m) is -5/2
3x - 7y = 10
-7y = -3x + 10
y = 3/7x - 10/7.....y int (b) = -10/7
so ur equation with slope(m) of - 5/2 and y int (b) of -10/7 is :
y = -5/2x - 10/7 <== slope intercept form
