Work out the gradient of the straight line that passes through (2,6) and (6,12)
Furkat [3]

Answer:

The gradient of the straight line that passes through (2, 6) and (6, 12) is m = \frac{3}{2}.

Step-by-step explanation:

Mathematically speaking, lines are represented by following first-order polynomials of the form:

y = b + m\cdot x (1)

Where:

x - Independent variable.

y - Dependent variable.

m - Slope.

b - Intercept.

The gradient of the function is represented by the first derivative of the function:

y' = m

Then, we conclude that the gradient of the staight line is the slope. According to Euclidean Geometry, a line can be form after knowing the locations of two distinct points on plane. By definition of secant line, we calculate the slope:

m = \frac{y_{B}-y_{A}}{x_{B}-x_{A}} (2)

Where:

x_{A}, y_{A} - Coordinates of point A.

x_{B}, y_{B} - Coordinates of point B.

If we know that A(x,y) = (2,6) and B(x,y) = (6,12), then the gradient of the straight line is:

m = \frac{12-6}{6-2}

m = \frac{6}{4}

m = \frac{3}{2}

The gradient of the straight line that passes through (2, 6) and (6, 12) is m = \frac{3}{2}.

Two angles are supplementary if the sum of their measures is 180 degrees. find two supplementary angles such that the smaller is
kaheart [24]
If the larger angle is x and the smaller angle is y, y=(1/2)x+30 since it's 30 more than 1/2 of it. In addition, x+y=180 since they are supplementary. Plugging y=(1/2)x+30 into that, we get x+x/2+30=180=1.5x+30. Subtracting 30 from both sides, we get 1.5x=150. Next, we can divide both sides by 1.5 to get x=100 and y=(1/2)*100+30=50+30=80
