Oh boy, this sounds like a mess. But I'll do my best to help you out.
Question #8 is asking to classify if the following equation is a slope intercept form or not.
I'm sure you should have learned about what a slope intercept form by now but its general equation is: y = mx + b
The "y" is just a single variable and must stay at its own value (one).
Examples of slope intercept form:
y = 48x + 3
y = -65x +10
y = 9x - 5
Now having this in mind, answer the questions.
4x + 2y = 12 is NOT slope-intercept form because it has too many variables on the left side of the =.
2y = 18x + 8 is also NOT slope-intercept form because it has "2" next to the "y" and there should only be a "y" in the left side of the =.
y = 6x - 1 and y = 1/2x + 3 ARE slope-intercept form because it follows the concept structure.
Now for the other question, you need to substitute the x values to the 3x - 1 equation, solve for the equation, then set up the final coordination.
x 3x - 1 y (x,y)
-2 3(-2) - 1 -7 (-2, -7)
-1 3(-1) - 1 -4 (-1, -4)
0 3(0) - 1 -1 (0, -1)
1 3(1) - 1 2 (1, 2)
2 3(2) - 1 5 (2, 5)
The bold points are to be plotted in the graph (I'm sure you know how to do that).
Also gaslighting ain't cool
Cheers :)
