How do you find the slope intercept form for a slope that is -2 passing through points (4,-3)

1 answer:

8 0

To find the slope intercept form, you plug in the slope and the points given and find whats missing
y=mx+b
slope is -2
given points are (4,-3)

-3=-2(4)+b (multiply -2 and 4)
-3=-8+b (add 8 to both sides)
5=b

so the equation for the slope intercept form would be
y=-2x+5

Answer:

z=24 y=5 x=12

Step-by-step explanation:

x+8=20 x=20-8 x=12

z+1=25 z=25-1 z=24

y+10=15 y=15-10 y=5

The length of a rectangle is 59 inches greater than twice the width. If the diagonal is 2 inches more than the length, find the

Paul [167]

So.. hmm notice the picture here

we know the length is 59 more than twice the width,
twice the width, 2 * w, or 2w
59 more than that
2w + 59

we also know that, whatever that is, the diagonal of it is,
2 more inches than that, or
(2w + 59) + 2

now.. use the pythagorean theorem
$\bf c^2=a^2+b^2\implies \qquad 
\begin{cases}
a=2w+59\\
b=w\\
c=(2w+59)+2\to 2w+61
\end{cases}
\\\\\\
(2w+61)^2=(2w+59)^2+(w)^2
\\ \qquad\qquad \uparrow\qquad \qquad\qquad \qquad \uparrow \\
\textit{expand using binomial theorem, or FOIL}$

you'd end up with a quadratic, after simplifying, solve for "w"
