What's the slope and y-intercept of the equation 4x + 2y = 8?
zepelin [54]

Answer:

m= - 2, b = 4

Step-by-step explanation:

structure of a linear equation

y = mx + c

m = gradient / slope

c = intercept

<em>convert</em><em> </em><em>the </em><em>given </em><em>equation</em><em> </em><em>according </em><em>to</em><em> </em><em>this</em><em> </em><em>structure</em><em> </em><em>of</em><em> </em><em>linear </em><em>equations</em><em> </em>

4x+2y = 8

2y = -4x + 8

y = -2x +4

<em>according</em><em> </em><em>to</em><em> </em><em>this </em><em>intercept</em><em> </em><em>is </em><em>4</em><em> </em><em>and </em><em>slope </em><em>is </em><em>-</em><em>2</em>

Write the point-slope form of the given line that passes through the points (0, 3) and (4, 0). Identify (x1, y1) as the x-interc
Sindrei [870]
Now, bear in mind that, when the y-axis gets intercepted, x = 0, therefore 0,3 is really the y-intercept.

and when the x-axis gets intercepted, y = 0, therefore 4,0 is the x-intercept, thus we will use this one in the point-slope form then.

\bf \begin{array}{lllll}&#10;&x_1&y_1&x_2&y_2\\&#10;%   (a,b)&#10;&({{ 0}}\quad ,&{{ 3}})\quad &#10;%   (c,d)&#10;&({{ 4}}\quad ,&{{ 0}})&#10;\end{array}&#10;\\\\\\&#10;% slope  = m&#10;slope = {{ m}}= \cfrac{rise}{run} \implies &#10;\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{0-3}{4-0}\implies -\cfrac{3}{4}&#10;\\\\\\&#10;% point-slope intercept&#10;\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-0=-\cfrac{3}{4}(x-4)

Which is an equation of a circle with center (-10, 6) and radius 8?
kupik [55]
An equation of a circle:

(x - a)² + (y - b)² = r²

(a; b) - a coordinates of a center
r - a radius

r = 8; (-10; 6) ⇒ a = -10 and b = 6

subtitute

(x - (-10))² + (y - 6)² = 8²

Answer: (x + 10)² + (y - 6)² = 64
