hope this helps :)
Use PEMDAS to figure out the order of operations:

Solve (-4 + -6) first, as this is in parentheses:
Solve 5.3 * -10 next, as this is multiplication:
Now we can solve the equation:
The answer is 63.
The answer is 2x+6
Explanation: 2 times 3 is 6 and 2 times x is 2x
The equation for working out the slope of a linear line is: , where x and y are the coordinate pairs.
So just pick two of the purple dots on the graph and fill in the equation.
I'll pick the dot that's (-4, 1) and (4, -7).
Now I just do , which is just when simplified.
