we know the x-intercept of the line is 1, recall that an x-intercept is when the graph intercepts or touches the x-axis, and when that happens, y = 0, so the point is really x = 1, y = 0, namely (1,0). We also know another point on the line, is (-2, 9).


\bf \stackrel{x-intercept}{(\stackrel{x_1}{1}~,~\stackrel{y_1}{0})}\qquad  (\stackrel{x_2}{-2}~,~\stackrel{y_2}{9}) \\\\\\ slope =  m\implies  \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{9-0}{-2-1}\implies \cfrac{9}{-3}\implies -3 \\\\\\ \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-0=-3(x-1) \\\\\\ ~\hspace{10em}y=-3x+3

Answer:

4

Step-by-step explanation:

multiply 10 by w and 3

equation becomes 10w+30=70

subtract 30 by both sides

equation becomes 10w=40

divide both sides by 10

equation becomes w=4

your answer is 4!

Answer:

178.3 mm²

Step-by-step explanation:

Surface area = Base area + 3 x side triangles area

Sₐ = 43.3 + 3 x (1/2 x (10 x 9)) = 43.3 + (3 x 45) = 178.3

Answer:

\:\mathrm{First\: problem:\:}-2,\\\:\mathrm{Second\: problem:\: }-3

Step-by-step explanation:

The slope of a line passing through points (x_1, y_1) and (x_2, y_2) is:

m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}

Plugging in any two points in the table we have:

<u>First problem:</u>

<u />m=\frac{1-5}{2-0}=\frac{-4}{2}=\fbox{$-2$}<u />

<u>Second problem:</u>

<u />m=\frac{-1-5}{2-0}=\frac{-6}{2}=\fbox{$-3$}<u />
