7x - 3y =42
for X = 0, y = 42/3 = 14
for y = 0, x = 42/7 = 6
So, the line passes through the two points on x-y diagram (0, 14) and (6, 0)

What is the slope-intercept form of 7x-3y equals 4
3y = 4x + 9 -4x + 3y = 9 is the standard form
-4x + 3y = 9
Put in this form. Y =mX + c X + 3Y - 6 = 0 X + 3Y = 6 3Y = - X + 6 Y = - (1/3)X + 2 --------------------- slope(m) = - 1/3 ------------------------
9x+3y = 6 3y = -9x+6 y = -3x+2 which is now in slope-intercept form
