Find Z1 in trig form z1= (-3+4i)
Eva8 [605]

Answer:

i = \frac{1}{4} z +\frac{3}{4}

Step-by-step explanation:

z^{1}=−3+4i

4i−3=z

4i−3+3=z+3

4i=z+3

Find the slope of the given line on the graph. REMEMBER: Rise over run! <br> Pls show work!
Leviafan [203]

Answer:

the slope is -\frac{1}{3}

Step-by-step explanation:

Notice that you are given two points to use for the slope calculation:

(x_1,y_1)=(-4,4) \,\,and\,\, (x_2,y_2)=(5,1)

So we use the formula for the slope of a line given two points:

slope\,=\,\frac{y_2-y_1}{x_2-x_1} \\slope\,=\,\frac{1-4}{5-(-4)} \\slope\,=\,\frac{-3}{9} \\slope\,=\,-\frac{1}{3} \\

write an equation in point-slope form for the line through the given point with the given slope (10,-9);m=-2​
fgiga [73]

Answer:

The answer is

<h2>y + 9 =  - 2(x - 10)</h2>

Step-by-step explanation:

To find the equation of a line given a point and slope we use the formula

<h3>y - y1 = m(x - x1)</h3>

where

m is the slope

( x1 , y1) is the point

From the question

Slope / m = - 2

The point is ( 10, - 9)

Substitute the values into the above formula

That's the final answer is

<h3>y + 9 =  - 2(x - 10)</h3>

Hope this helps you
