What are the slope and y intercept of the line described by the equation y=-4/5x -10
rodikova [14]

The slope is -\frac{4}{5} and y-intercept is -10

Step-by-step explanation:

Given equation is:

y = -\frac{4}{5}x-10

The given equation is in slope-intercept form

General form of slope-intercept form of equation of line is:

y = mx+b

Here

m is the slope

b is the y-intercept

So,

comparing both equation we get

The coefficients of x

m = -\frac{4}{5}

And

b = -10

Hence,

The slope is -\frac{4}{5} and y-intercept is -10

Keywords: Slope, equation of line

What is the area of the figure shown?
musickatia [10]

Check the picture below.

now, we're making an assumption that, the two blue shaded region are equal in shape, and thus if that's so, that area above the 14 is 6 and below it is also 6, 14 + 6 + 6 = 26.

so hmm if we simply get the area of the trapezoid and subtract the area of the yellow triangle and the area of the cyan triangle, what's leftover is what we didn't subtract, namely the shaded region.

\textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} h~~=height\\ a,b=\stackrel{parallel~sides}{bases~\hfill }\\[-0.5em] \hrulefill\\ h=15\\ a=14\\ b=26 \end{cases}\implies A=\cfrac{15(14+26)}{2}\implies A=300 \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{\Large Areas}}{\stackrel{trapezoid}{300}~~ - ~~\stackrel{yellow~triangle}{\cfrac{1}{2}(26)(9)}~~ - ~~\stackrel{cyan~triangle}{\cfrac{1}{2}(15)(6)}} \\\\\\ 300~~ - ~~117~~ - ~~45\implies 138\qquad \textit{blue shaded area}

5(8-70) + 29 nt (n=4
IRINA_888 [86]

Answer:

5 x 8 = 40

5 x -70 = -350

40 - 350

29 x 4 = 116t

therefore it would be 40 - 350 + 116t

I think
