I assume you mean y= 3x/4?
you could sub in x values, (1,2,3) into the equation to find the y coordinates, and then you'll know both the x and y coordinates...
or you could just find one point, and then use the slope (3/4) to determine the next point... (3/4) means to find the next point, you go up by 3, and move over 4
unless you meant y^3/4x....

The y-intercept of the graph of 4x + 2y =12 is probably 6
Your question is not clear. Do you mean y = 4x? That is a straight line connecting (0,0) through (1,4)

y = 4x-3
-3
To determine which graph represents the equations (y = 4x + 3) and (y = x + 3), note that (y = 4x + 3) is a straight line with a steeper slope of 4, while (y = x + 3) has a slope of 1. The line (y = 4x + 3) rises more sharply than (y = x + 3). Therefore, the graph with the steeper line corresponds to (y = 4x + 3), while the less steep line corresponds to (y = x + 3).

y = -4x The y-intercept is zero. That is, the graph passes through the origin.
3y - 4x = 24 The first step is to write it in the standard form (y=mx + c) 3y = 4x + 24 y = (4x + 24)/3 y = 4x/3 + 8 The y-intercept is 8 and the slope/gradient is 4/3
The y-intercept of the graph of 4x + 2y =12 is probably 6
To shift the graph of y = 4x + 7 down, you would subtract a constant from the equation. In this case, you would subtract 7 from the equation to shift it downward. The new equation would be y = 4x. This would shift the entire graph downward by 7 units along the y-axis.

If the equation is changed from ( y = 4x + 3 ) to ( y = -4x + 3 ), the graph will reflect across the y-axis. The original line has a positive slope of 4, indicating it rises steeply as x increases, while the new line has a negative slope of -4, indicating it falls steeply as x increases. Both lines will have the same y-intercept at (0, 3), but their orientations will be opposite.
Find the two X intercepts. Set = to 0 4X + 3 = 0 X = -3/4 ( while Y = 3) 4X - 2 = 0 X = 1/2 ( while Y = -2) Now you have two points for each parallel line and can draw the graph
y = -x2 - 4x - 3. The constant, 3, tells us where the graph would hit the y-axis. In this case, it would hit the y-axis at -3. Solving the equation y = -(x2 + 4x + 3) ; y=-(x+3)(x+1) Therefore hits the x-axis at -3 and -1. Since it's a parabola (x2), the graph can either start from the top, or from the bottom. An equation starting with ax2 will start from the top, and an equation with -ax2 will start from the bottom. So therefore, the graph starts from the bottom of the page, goes from -3 and -1 on the x-axis and intercepts the y-axis at -3.
