5.3 you do your 9-3.7 and then add 9 +-3.7

9-(-3.7) =
9 + 3.7 = 12.7

-4.6 + 5.3 is the same thing as:
5.3 - 4.6 which = 0.7.

hope this helped! (:

3. Try It #3 Write the point-slope form of an equation of a line with a slope of -2 that passes through the point (-2,2). Then r

vova2212 [387]

Answer:

Point-slope form of equation given as $y-2=-2(x+2)$ .

Slope-intercept form of equation is given as $y=-2 x-2$ .

Step-by-step explanation:

In the question, it is given that the slope of a line is -2 and it passes from (-2,2).

It is asked to write the point-slope form of the equation and rewrite it as slope-intercept form.

To do so, first find the values which are given in the question and put it in the formula of point-slope form. Simplify the equation to rewrite as slope-intercept form.

Step 1 of 2

Passing point of the line is (-2,2).

Hence, $x_{1}=-2$ and

$y_{1}=2 \text {. }$

Also, the slope of the line is -2.

Hence, m=-2

Substitute the above values in point-slope form of equation given by $y-y_{1}=m\left(x-x_{1}\right)$

$\begin{aligned}&y-y_{1}=m\left(x-x_{1}\right) \\&y-2=-2(x-(-2) \\&y-2=-2(x+2)\end{aligned}$

Hence, point-slope form of equation given as y-2=-2(x+2).

Step 2 of 2

Solve y-2=-2(x+2) to write it as slope-intercept form given by y=mx+c.

$\begin{aligned}&y-2=-2(x+2) \\&y-2=-2 x-4 \\&y=-2 x-4+2 \\&y=-2 x-2\end{aligned}$

Hence, slope-intercept form of equation is given as y=-2x-2.

If f ( x ) = 4 x 2 − 2 x + 3 f ( x ) = 4 x 2 - 2 x + 3 , find f ' ( − 5 ) f ′ ( - 5 ) . Use this to find the equation of the tan

Troyanec [42]

$\bf f(x)=4x^2-2x+3\implies \left.\cfrac{dy}{dx}=8x-2 \right|_{x=-5}\implies -42 \\\\
-------------------------------\\\\
(-5,113)\qquad \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-113=-42[x-(-5)]
\\\\\\
y-113=-42(x+5)\implies y-113=-42x-210
\\\\\\
y=-42x-97$
