The height of a person and the person's age, is the relationship linear?

PolarNik [594]

Liniear means that they go up at a constant rate
example, every year you grow 2 inches and you started at 8 inches tall
that would be linear
but that is not the case
generally, the younger you are, the faster you grow
as you age, you don't grow as much anymore :(

so no, it is not linear

Write an equation of the line that passes through (18, 2) and is parallel to the line 3y−x=−12

miskamm [114]

keeping in mind that parallel lines have the same exact slope, hmmmm what's the slope of the line above anyway?

$\bf 3y-x=-12\implies 3y=x-12\implies y=\cfrac{x-12}{3}\implies y = \cfrac{x}{3}-\cfrac{12}{3} \\\\\\ y = \stackrel{\stackrel{m}{\downarrow }}{\cfrac{1}{3}}x-4\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}$

so we're really looking for the equation of a line whose slope is 1/3 and runs through (18,2)

$\bf (\stackrel{x_1}{18}~,~\stackrel{y_1}{2})~\hspace{10em} \stackrel{slope}{m}\implies \cfrac{1}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{2}=\stackrel{m}{\cfrac{1}{3}}(x-\stackrel{x_1}{18}) \\\\\\ y-2=\cfrac{1}{3}x-6\implies y=\cfrac{1}{3}x-4$

Find the slope of a line that passes through a point of (5,-2) and point (1,-3) m=

Marat540 [252]

Here, (x1, y1) = (5,-2)
(x2, y2) = (1, -3)

(y2-y1) = m(x2-x1)
-3-(-2) = m(1-5)
-1 = m(-4)
m = 1/4

So, your final answer is 1/4

Hope this helps!
