Find the slope of the line whose equation is 2x – 4y = 10. How do I find the slope?

To find the slope, u need to put the equation in y = mx + b form, where m will be ur slope.

2x - 4y = 10 ... subtract 2x from both sides
-4y = -2x + 10...divide both sides by -4
y = (-2/-4)x + (-10/4)
y = 1/2x - 5/2

y = mx + b
y = (1/2)x - 5/2
the slope(m) = 1/2

Find the area of abc. round your answer to the nearest tenth. b=87, a = 10.1, c = 9.8
Advocard [28]
The area of the triangle can be calculated through the equation,
             A = sqrt ((s)(s - a)(s - b)(s - c))
where A is area, s is the semiperimeter ((a + b + c)/2), a, b, and c are the sides given above.

The presented equation above is the Heron's formula.

Substituting the known values,
             s = (8.7 + 10.1 + 9.8) / 2
              s = 14.3

    A = sqrt ((14.3)(14.3 - 8.7)(14.3 - 10.1)(14.3 - 9.8))
           <em>A = 38.9 units squared

</em>
Thus, the answer to this item is not among the choices. <em>
