x = 1
2x+5y=20 Solve for y -2x -2x 5y=20-2x 5 5 5 y=4-2x 5
0 = -2x + 5y - 15 -5y = -2x - 15 y = 2x/5 + 3
If you mean 2x+5y = -10 then the y intercept is -2
2X - 5Y = 10 ???? If so. 2X - 5Y = 10 - 5Y = - 2X + 10 Y = (2/5)X - 2 ================

2x-5y = -10 -5y = -2x-10 y = 2/5x+2 which is in slope intercept form
Put in this form. Y = mX + c 2X - 5Y = 10 - 5Y = - 2X + 10 Y = (2/5)X - 2 ================
-5y +2x = -10 -5y = -2x -10 y = 2/5x +2 So the slope = 2/5 and the y intercept = 2
Answer : x = 6 : y = -4.62x = 12 therefore x = 6 : substituting in x - 5y = 29 gives :-6 - 5y = 29 : 5y = 6 - 29 = -23 : y = -23/5 : y = - 4.6
2x + 5y = 10Subtract 2x from each side:5y = -2x + 10Divide each side by 5:y = - (2/5)x + 2Slop = - (2/5)Y-intercept = 2
y = -6
2x +n5y=12
