I don’t know the rest but number seven is n
Answer:
x=3
Step-by-step explanation:
It is pretty simple.
x = 3 means literally just a vertical line at +3 on the x-axis.
In contrast, y = 3 would mean a horizontal line at +3 on the y-axis.
If you would like to see this for yourself pull-up desmos on your browser and type it into the graphing calculator of desmos.
Replace X and Y in the given equations and see if they are true:
2(5) + 2(1) = 10+2 = 12... does not equal 11 So this in not right.
2(5) +3(1) = 10 + 3 = 13 this is correct.
The answer would be: 2x+3y=13
Answer: y+1=-7 (x-5)
Step-by-step explanation:
The formula for point-slope form is y-y1= m (x-x1)
Step 1- Finding the slope by using formula 
:
(5,-1) (6,-8) or (x1, y1) (x2, y2)
-8+1 = -7
6-5 = 1
Slope + -7/1 or -7
Step 2- Then insert numbers in point slope form:
y-y1 = m(x-x1)
y+1 = -7 (x-5)
