Step-by-step explanation:
- All you have to do it substitute the x in the rule with the x in the table. Let's do the first one in the steps below.
- Write the equation with the x value: y = -10(-1) + 1
- -10 × -1 = 10
- Plug 10 in: y = 10 + 1
- 10 + 1 = 11
- So, y = 11
- Now that you know how to find the rest, go ahead and do it (my answer doesn't show the work, but the answers are in the screenshot below)
I hope this helps!

Answer:
3. 2x + y = −1
Step-by-step explanation:
To find the equation of the line, we write it first in the slope-intercept form:
where
m is the slope
q is the y-intercept
From the graph, we see that the line crosses the y-axis at y = -1, so the y-intercept is -1:
Now we have to find the slope, by calculating the rate of change of the line through 2 points:
Taking the two points at (-2,3) and (1,-3), we find:
So the equation of the line is
Now we have to re-arrange it in the standard form, so in the form
where a, b and c are integer numbers.
To do that, we simply add +2x on both sides of the equation of the line in the slope-intercept form, and we get:
So, option 3).
