Another Asap question plzzzz!!!!!!!!!!

Hunter-Best [27]

Answer:

(0,-4)

(2,-1)

The first point because it is the y-intercept

second point because it is found our by 3/2 as the slope. slope is rise/run. so you rise three and move to the side 2. as is the point (2,-1)

Hope this helps

I’m not good with geometry please help

Answer:

The value of t is 41

Step-by-step explanation:

The figure is 5 sided polygon.

The sum of interior angles of 'n' sided polygon is given by,

= $180(n-2) degrees$

here, n=5,

thus, $180(5-2) = 180(3) = 540 degrees$

All the given angles have linear pair in the polygon.

$(180-2t)+(180-3t)+(180-42)+(180-52)+(180-61) = 540$

$5t = 205$

Thus, t = 41

What is the slope line that passes through the points (10, 8) and (-15, 18)? Write your answer in simplest form

klasskru [66]

Answer: $y=-\frac{2}{5}x+12$

y = mx + b

m = slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{18-8}{-15-10}=\frac{10}{-25}=\frac{2(5)}{-5(5)}=-\frac{2}{5}$

The y-intercept(b) can be found by substituting a point into the function.

$y = -\frac{2}{5}x + b \\\\8=-\frac{2}{5}(10) + b\\\\8=-4+b\\\\b=8+4=12$

Therefore, the function is:

$y=-\frac{2}{5}x+12$
