How do you work out the gradient of a line?

1 answer:

6 0

Step-by-step explanation:

The gradient of the line = (change in y-coordinate)/(change in x-coordinate) . We can, of course, use this to find the equation of the line. Since the line crosses the y-axis when y = 3, the equation of this graph is y = ½x + 3 . To find the gradient of a curve, you must draw an accurate sketch of the curve.

The square abcd has side length 10cm. E is the midpoint of BC. Work out the length of DE. Answer to 1 decimal place.

Levart [38]

-- DEC is a right triangle.

-- DC is one side of the square = 10 cm
-- EC is half the side of the square = 5 cm
-- DE is the hypotenuse = square root of (5² + 10²) = √(125 cm²) .

<em>-- Truncated</em> to one decimal place, that's 11.1 cm.

<em>-- Rounded</em> to one decimal place, it's 11.2 cm.
