Y = 2.5X ( + 0 )
So, zero is the Y intercept of this function.
Simplify 5y = 25x - 15 by dividing each term by 5 to produce y = 5x - 3. By definition, the y-intercept of this equation is the value of y when x = 0, in this instance -3.
y=x+1 there for answer is 2
y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.

The graph of [ y = -3x ] is a straight line, through the origin, with slope of -3 .
x=.293 y=11.328
No translation will invert a quadratic graph.

Simplify 5y = 25x - 15 by dividing each term by 5 to produce y = 5x - 3. By definition, the y-intercept of this equation is the value of y when x = 0, in this instance -3.
The graph shifts downward (negative y) by 9 units.
First, reflect the graph of y = x² in the x-axis (line y = 0) to obtain the graph of y = -x²; then second, shift it 3 units up to obtain the graph of y = -x² + 3.
y= -5

-25x+y=65-25(0)+y=65y=65When finding a y-intercept you replace the value of xwith 0. The same goes for finding the x-intercept, you replace the value of y with 0 and simplify the equation.
y=x+1 there for answer is 2
y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.
y = -4x The y-intercept is zero. That is, the graph passes through the origin.
