Q. Find the y-intercept of the line 15x+18y=−20. Write your answer as an integer or as a simplified proper or improper fraction, not as an ordered pair.
Set x to 0: To find the y-intercept of the line, we need to set x to 0 and solve for y.Substitute x=0 into the equation 15x+18y=−20.15(0)+18y=−2018y=−20
Solve for y: Now, we divide both sides of the equation by 18 to solve for y.1818y=18−20y=18−20
Divide by 18: Simplify the fraction −1820 to its simplest form.Both the numerator and the denominator can be divided by 2.y=(18/2)(−20/2)y=−910
