I got 6.3 not sure if Im right

Step 1 : subtract 1 from both sides

Step 2 : Divide both sides by 3


Step 3 : Find the square root of 9

x= (-3,3)
remember negative × negative = positive
Always start with what’s in the parentheses:)
ABOUT POINT SLOPE FORM:
- y - Y1 = m(x - X1)
- m represents the slope
- Y1 & X1 is a point
- The form allows you to identify the slope & the point on the line
y - Y1 = m(x - X1)
y - 8 = -1/10(x - 1) -- IN POINT SLOPE FORM
Hope this helps you!!! :)
