You need to find the slope of the line too. they use m to represent slope.
point slope equation is y - y1 = m(x -x1)
they said to use point (-2, -2)
y -(-2) = 1(x -(-2))
y +2 = 1(x +2)
point slope equation is y - y1 = m(x -x1)
they said to use point (-2, -2)
y -(-2) = 1(x -(-2))
y +2 = 1(x +2)
The equation to represent the relationship of the weights shown on the scale s
The weights are given as:
The total weight on one side, where there are 4 small squares and 3 large squares is:
The total weight on the other side, where there are 2 small squares, 2 large squares and 1 triangle is:
The weight of the triangle is x.
So, we have:
The weights on both sides are equal, because the scale is balanced.
So, we have:
Hence, the equation is
