What is the slope intercept form equation of the line that passes through (3, 4) and (5, 16)?
luda_lava [24]

It is convenient to start with the 2-point form of the equation for a line.

... y - y1 = (y2 - y1)/(x2 - x1)×(x - x1)

Either point can be (x1, y1), and the other can be (x2, y2). If we take them in order, we get

... y - 4 = (16 - 4)/(5 - 3)×(x - 3) . . . . . fill in the two points

... y = 12/2(x -3) +4 . . . . . . . . . . . . . . add 4, simpliffy a bit

... y = 6x -18 +4 . . . . . . . . . . . . . . . . . eliminate parentheses

... y = 6x -14 . . . . . . . . . . . . . . . . . . . . put in slope-intercept form

tonya is 1.3 meters tall. she stands 7 meters in front of a tree and casts a shadow of 1.8 meters long. how tall is the tree
butalik [34]

Answer:

The tree is  6.36  meters tall.

Explanation:  Let AB is tree of height  h t = ?  and CD is Tonya  h g = 1.3  meter tall at  A C =  7 meters in front of tree . The shadow  C E = 1.8  meters long .  So two similar triangles are formed , one  Δ A E B and other  Δ C E D . So  A B C D = A E C E  or  h t h g = A E A C  or   h t h g = A C + C E  AC  or  h t  1.3 = 7 + 1.8 1.8  or  h t = 8.8 ⋅ 1.3 1.8 ≈ 6.36 ( 2 d p )m

The tree is  6.36  meter tall.
