Find the equation of a line that passes through the given point(-3,-4) and (2,11)

Mathematics
1 answer:
valentina_108 [34]3 years ago
6 0

Answer:

y = 3x + 5

Step-by-step explanation:

The slope of this line is (11 - (-4)) /  (2 - (-3))

= 15/5 = 3

Now we use the point slope form of an equation:-

y - y1 = m(x - x1)

y - 11 = 3(x - 2)

y - 11 = 3x - 6

y = 3x + 5  (answer)

Angle 1 and angle 3 are complementary and angle 1 =~ angle 2 which one of these statements will always be true
n200080 [17]
Can you add the options?
Also since the options aren't there I'll just help set up.
So angle 1 and angle 3 add up to 90 degrees. Angle 1 and Angle 2 are equal so whatever option has something around those lines is correct.

A line includes the points (9, -7) and (-6, -2). What is its equation in slope-intercept form?
Rus_ich [418]

Answer:

y=\frac{-1}{3}x-4

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

<em>m</em> - slope

<em>b </em>- y-intercept

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step 1: Define

Point (9, -7)

Point (-6, -2)

Step 2: Find slope <em>m</em>

<em />m=\frac{-2-(-7)}{-6-9}<em />

<em />m=\frac{-2+7}{-15}<em />

<em />m=\frac{5}{-15}<em />

<em />m=\frac{-1}{3}<em />

y=\frac{-1}{3}x+b

Step 3: Find y-intercept <em>b</em>

<em />-7=\frac{-1}{3}(9)+b<em />

<em />-7=-3+b<em />

<em />-4=b<em />

<em />

Step 4: Write linear equation in slope-intercept form

y=\frac{-1}{3}x-4

10) Find the measure of angle D. Hint: you must do two math problems to solve
NISA [10]

Answer:

Option A.) 43°

Step-by-step explanation:

Part 10)

step 1

Find the length of side EG

see the attached figure to better understand the problem

we know that

In the right triangle EGF

cos(65^o)=\frac{EG}{EF} ----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

cos(65^o)=\frac{EG}{11}

solve for EG

EG=(11)cos(65^o)\\EG=4.65\ cm

step 2

Find the measure of angle D

In the right triangle DEG

tan(D)=\frac{EG}{DG} ----> by TOA (opposite side divided by adjacent side)

substitute the given values

tan(D)=\frac{4.65}{5}\\\\D=tan^{-1}(\frac{4.65}{5})=43^o
