The y-intercept is -6.
When identifying parts of a slope-intercept equation, we can note that:
• The coefficient is the slope (represented by m)
• The constant is the y-intercept (represented by b)
In this equation, the constant (the integer by itself) is -6. The slope (the coefficient represented with a variable of x beside it) is 4. (0,-6) is the point on a coordinate plane in which the graphed line crosses the y-axis.
