Step-by-step explanation:
AC²=AB²+BC²
=(7)²+(13)²
=49+169= 218
AC=√218
= 14.7ft
therefore the original height of the tree
=7+14.7
=21.7ft

Answer <u>(assuming it can be in slope-intercept form)</u>:
Step-by-step explanation:
1) First, find the slope of the line between the two points by using the slope formula, . Substitute the x and y values of the given points into the formula and solve:
Thus, the slope of the line is .
2) Next, use the point-slope formula to write the equation of the line in point-slope form. Substitute values for
,
, and
in the formula.
Since represents the slope, substitute
in its place. Since
and
represent the x and y values of one point the line intersects, choose any of the given points (it doesn't matter which one, it will equal the same thing) and substitute its x and y values into the formula as well. (I chose (-2,0), as seen below.) Then, isolate y and expand the right side in the resulting equation to find the equation of the line in slope-intercept form:
