Part A. To write the equation 5=10x-5y in slope-intercept form, we need to isolate y on one side of the equation. First, we'll add 5y to both sides of the equation:
5 + 5y = 10x
Next, we'll subtract 5 from both sides of the equation:
5y = 10x - 5
Finally, we'll divide both sides of the equation by 5:
y = 2x - 1
Therefore, the equation 5=10x-5y in slope-intercept form is y = 2x - 1.
Part B. The y-intercept is the point where the line crosses the y-axis. In slope-intercept form, the y-intercept is the constant term. In this equation, the constant term is -1. Therefore, the y-intercept is -1.
