Well the y-intercept is where a line crosses the y-axis y=-4x-6 think of it as y=mx+b m is always going to be your slope b is always going to be your y-intercept y-intercept of y=-4x-6 is -6
First of all, to make this problems more clearly. I will use slope-intercept form in this case which is y=mx+b where m represent slope and b represent y-intercept Then, we analyze the same to y=-4x-6 m=-5 y=-6 or y-intercept=-6. As a result, the y-intercept is -6. Hope it help!
