graph the inequality...
y > –5x + 3
I need help to know how to graph this - unsure how and I have to choose between 4 graphs that are shaded....
this makes no sens
u all all wrong

ruby is right!!
To graph the inequality y > -5x + 3, you can follow these steps:
Step 1: Start by graphing the line y = -5x + 3 as if it were an equation. This line has a slope of -5 and a y-intercept of 3. You can plot the y-intercept (0, 3), then use the slope to find more points. For example, if you move one unit to the right and five units down, you can plot the point (1, -2). Connect the points to draw the line.
Step 2: Since the symbol in the inequality is > (greater than), you need to determine which side of the line to shade. To do this, you can choose a test point that is not on the line. The easiest test point to use is (0, 0).
Step 3: Substitute the test point (0, 0) into the inequality y > -5x + 3. Evaluate if the test point satisfies the inequality or not. If it does, then shade the side of the line containing the test point. If it does not satisfy the inequality, shade the other side.
In this case, substituting (0, 0) into the inequality gives:
0 > -5(0) + 3
0 > 3
Since 0 is not greater than 3, the test point (0, 0) does not satisfy the inequality. Therefore, you should shade the side of the line that does not contain the test point (0, 0).
Based on this process, you can now choose the correct graph among the four options provided.
