NARA [144]3 years ago

The equation of line that passes through the points (-3,-1) and

(-6,3) is:

y=-\frac{4}{3}x-5

Step-by-step explanation:

Given points are:

(-3,-1) =(x1,y1)

(-6,3)=(x2,y2)

The slope-intercept form of equation of line is:

y=mx+b

We have to find the slope first

m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{3-(-1)}{-6-(-3)}\\=\frac{3+1}{-6+3}\\=\frac{4}{-3}

Putting the value of slope in the slope intercept form

y=-\frac{4}{3}x+b

To find the value of b, putting the point (-3,-1) in the equation

-1=-\frac{4}{3}(-3)+b\\-1= 4+b\\b=-4-1\\b=-5

Putting the values of b and m

y=-\frac{4}{3}x-5

The equation of line that passes through the points (-3,-1) and

(-6,3) is:

y=-\frac{4}{3}x-5

Which values of m and b will create a system of equations with no solution? Select two options. y = mx + b y = –2x + A system of
Nuetrik [128]

Answer:

m = -2 and b = -1/3

m = -2 and b = -2/3.

Step-by-step explanation:

y = -2x - 1/3

y = -2x - 2/3

This system has no solutions because y cannot be 2 different values at once.

19. A spherical balloon has a circumference of 19cm. what is the approximate surface area of the balloon to the nearest square c
Tamiku [17]
The main formula of a spherical surface area is SA= 4 x Pi x r²
the circumference is C= 19cm =2 Pi r, so r = C/ 2Pi = 19 / 6.28 =3.02cm
so the surface area can be found by computing
SA= 4x 3.14x 3.02² =114.5, the nearest square centimeter is <span>A) 114 cm^2</span>
