What is the equation of the line that passes through the points (–12, –8) and (–17, –16)?
horsena [70]

Answer:

<em>firstly</em><em> find</em><em> the</em><em> gradient</em><em> given</em><em> by</em><em> the</em><em> equation</em>

<em>m=</em><em>y2-y1</em><em>/</em><em>x2-x1</em>

<em>in this </em><em>case</em><em> </em><em>x1 </em><em>is </em><em>-</em><em>1</em><em>2</em><em>,</em><em>x2 </em><em>is </em><em>-</em><em>1</em><em>7</em><em>,</em><em> </em><em>y1 </em><em>is </em><em>-8 </em><em>and </em><em>y2 </em><em>is</em><em>-</em><em>1</em><em>6</em>

<em>m=</em><em>-</em><em>1</em><em>6</em><em>+</em><em>8</em><em>/</em><em>-</em><em>1</em><em>7</em><em>+</em><em>1</em><em>2</em>

<em> </em><em> </em><em> </em><em>=</em><em>-</em><em>8</em><em>/</em><em>-</em><em>5</em><em> </em><em>or1.</em><em>6</em>

<em>then</em><em> </em><em>use </em><em>the </em><em>equation</em>

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

y+8=1.6(x+12)

y+8=1.6x+19.2

y=1.6x+11.2

I hope this helps and sorry if it's wrong

\angle a∠aangle, a and \angle b∠bangle, b are complementary angles. \angle a∠aangle, a measures 59^\circ59
yanalaym [24]

Answer:

31°

Step-by-step explanation:

because angle a and angle b are complementary they equal 90 degrees in total

a+b=90

since angle a = 59°

59+b=90

so you use subtraction property of equality and subtract 59 from both side of the equal sign

59+b=90

-59    -59

b= 31°
