y = 1/2x - 2

Step-by-step explanation:

Slope: 1/2

Point: (0, -2)

y-intercept: -2 - (1/2)(0) = -2

Solve for w k=2b-5w/3k

nlexa [21]

$k = \frac{2b - 5w}{3k}$
$3k^{2} = 2b - 5w$
$3k^{2} + 5w = 2b$
$5w = 2b - 3k^{2}$
$w = \frac{2}{5}b - \frac{3}{5}k^{2}$

Find the slope of the line.

lorasvet [3.4K]

<h3>Given ↓</h3>

Two points that a line goes through

The line's slope

<h3>Calculations ↓</h3>

When we have two points that a line passes through and asked to determine the slope of the line, the slope formula is going to come in handy.

This is the formula :

$\boxed{\\\begin{minipage}{3cm}slope~formula~: \\ $\displaystyle\frac{y2-y1}{x2-x1}$ \\ \end{minipage}}$

y2 and y1 are y-coordinates, and x2 and x1 are x coordinates

Plug in the values :

$\boxed{\\\begin{minipage}{3cm}$\displaystyle\frac{0-(-7)}{7-0} $\end{minipage}}$

$\boxed{\\\begin{minipage}{3cm}$\displaystyle\frac{0+7}{7} \end{minipage}}$

Which simplifies to $^7/_7$ , or 1

<h3>Slope ↓</h3>

2(3 – 4a) + 5(a – 7)

PilotLPTM [1.2K]

Answer:

The answer is -(29+3a).

Step-by-step explanation:

=2(3-4a)+5(a-7)

= 6- 8a +5a -35

= 6-35-8a+5a

= -29-3a

= -(29+3a)

Identify the equation of a line in slope-intercept form that is perpendicular to y = -1/3 x + 2 and passes through (2, 1).

kari74 [83]

To get your answer, you will need to find the perpendicular slope for -1/3x which is just the opposite therefore it will be 3x. Your slope is 3x as perpendicular so use this slope to do point slope. Y-1=3(x-2). Distribute y-1=3x-6. Add 1 to both sides. (-1+1) (-6+1)=-5. So your equation in slope intercept form is y=3x-5. Going through the two points.

Hope this helps!
