Step-by-step explanation:
the most common form of line equation is
y = ax + b
a is the slope of the line. it is expressed as the ratio
y coordinate change / x coordinate change
when going from one point to the other.
b is the y-intercept (the y value when x = 0).
so, in our case, the slope is 2, the y-intercept is -3.
the y-intercept gives you the first point : (0, -3)
using the slope of 2 we know that for every unit x increases, y increases by 2.
so, you can pick a next point e.g. x = 2, which makes y = -3 + 2×2 = -3 + 4 = 1
that gives us (2, 1)
mark both points on the chart and then draw a straight line through both points.
We have the digit 6,228.
We need to find the values of 2s in the digit 6228.
First of all we need to split the digits as per their place values.
6 is at thousands place in the digits 6228, so the place value of 6 is 6000 
.
2 is at hundreds place in the digits 6228, so the place value of 2 is 200 
.
2 is also their at tens place in the digits 6228, so the place value of 2 is 20 
.
8 is at ones place in the digits 6228, so the place value of 8 is 
.
So, first 2 in the digits 6,228 is at hundreds place and the second 2 is at tens place.
You would basically go back and trace all your steps, that's what I do. And if your answer seems reasonable then you have the right answer but if your work doesn't match the answer than you've messed up.
I hope I helped if I did like my answer and comment down below thx
Your answer would be <span><span><span><span>5−7</span>+6</span>−3</span>−1</span>−<span>(<span>−8</span>) = 8</span>
