2y=8x What is the slope intercept form, slope, and y-intercept
kaheart [24]
Y-intercept: 0
Slope: 4

Explanation
Y-intercept is the number without the x which in this case is no number so it’s 0 so that’s where the point in the y axis goes

Slope is rise over run so if the equation is 2y = 8x then we can simplify this by dividing both sides by 2 which would be y = 4x so slope is 4/x. Which is basically 4/1 because the x means over one so up 4 units and to the right once


Hope this helps
