Find the equation of the line passing through the points (3, -2) and (4, 6). y=[?x +[]
1 answer:
The line equation : y=8x-26
<h3>Further explanation</h3>Given
The points (3, -2) and (4, 6)
Required
Line equation
Solution
General formula
y-y1 = m(x-x1)
or
y = mx + c
Where
m = straight-line gradient which is the slope of the line
x1, y1 = the Cartesian coordinate that is crossed by the line
c = constant
The formula for a gradient (m) between 2 points in a line
m = Δy / Δx
Input given values in formula :
(3, -2⇒)x1, y1
(4, 6)⇒x2, y2

Answer:
11. On the diagram of the area of sand dune development attached to the answer, draw a sketch showing the general side view of a sand dune formed by a wind blowing in the direction indicated. Your sketch should clearly show any variations in the slope of the sides of the dune.
[1] Allow 1 credit for a correct profile, showing both the windward and leeward sides of the same dune, and showing the steepest gradient on the leeward side. Acceptable responses include, but are not limited to, this example:
12. Allow 1 credit for a correct response. Acceptable responses include, but are not limited to, these examples:
The calcite cement would be chemically weathered and removed by infiltrating water.
It would be dissolved.
It will bubble.
