Find the y intercept of 12x-6y=36. No ordered pair. Numeric value only. pls help!!

Simone claims the initial value and y-intercept are the same thing on a graph. is she correct? if you know that a line has a slope of and a y-intercept of 7, what is the equation for that line in slope-intercept form?

Complex numbers multiply √-4 * √-25 and show all intermediate steps. alternative notation is sqrt(-4) * sqrt(-25).

Which shows the correct substitution of the values a, b and c from the equation 1=-2x+3x^2+1
