1/2y = 9x + 5
3x = 6 - 1/3y
y-intercept is a point where the graph of a function or relation intersects with the y-axis of the coordinate system.
OR
y-intercept is a point where x = 0
1 / 2 y = 9 x + 5 Multiply both sides by 2
y = 18 x + 10
for x = 0
y = 18 * 0 + 10 = 0 + 10 = 10
y-intercept = 10
3 x = 6 - 1 / 3 y Multiply both sides by 3
9 x = 18 - y Add y to both sides
9 x + y = 18 - y + y
9 x + y = 18 Subtract 9 x to both sides
9 x + y - 9 x = 18 - 9 x
y = - 9 x + 18
for x = 0
y = - 9 * 0 + 18 = 0 + 18 = 18
y-intercept = 18
Answer:
3x = 6 - 1 / 3 y
