Make a table of values for the equation.<br> y = 3x + 2
Rzqust [24]
Tables are easy to make when u have the equation. Just simply sub any number in for x and solve for y

y = 3x + 2...lets let x = 0
y = 3(0) + 2
y = 2.....so when x = 0, y = 2....(0,2)

y = 3x + 2....lets let x = 1
y = 3(1) + 2
y = 3 + 2
y = 5....so when x = 1, y = 5....(1,5)

y = 3x + 2.....let x = 2
y = 3(2) + 2
y = 6 + 2
y = 8....so when x = 2, y = 8...(2,8)

u can find more point if u need to...

now make a table..

         x            y
        0             2
        1             5
        2             8
and like I said, if u need more numbers for ur table, just do like I did above :)

I’m pretty sure it’s x=10 because
8x + 50 = 130
So we would subtract 50 from both sides so it would be 8x = 130 - 50 then it would give us 80 so now we have 8x =80, now we will need to divide the 8 on both sides to get x, so 80/8 equals 10
