The slope -intercept form of linear equation is y=mx+b.

Where m= slope and b=y-intercept.

Formula to find m is,

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

The line passes through (-1, 8) and (3, 16) . So, we can plug in x1=-1, y1=8, x2=3 and y2=16 in the above formula. So,

m=\frac{16-8}{3-(-1)}

m=\frac{8}{3+1}

m=\frac{8}{4}

So, m=2

Now we can plug in m=2, x=3 and y=16 in y=mx+b to get the value of b. So,

16=2*3+b

16=6+b

16-6=b

So, b=10.

polet [3.4K]

Answer:

Step-by-step explanation:

here you go mate :)

step 1

2(x + 4) = -6  solving for x

step 2

2(x + 4) = -6  simplify by distributing

2x+8=-6

step 3

2x+8=-6  subtract 8

2x=-14

step 4

2x=-14  look for the number that can divide them both like 2

2x/2=-14/2

answer

x=-7

When a spherical balloon is filled with air, it has a radius of 3 inches. Which of these gives the best estimate for the volume
marysya [2.9K]
By definition, the volume of a sphere is given by:
 V = (4/3) * (pi) * (r ^ 3)
 where,
 r: radius of the sphere.
 Substituting we have:
 V = (4/3) * (pi) * ((3) ^ 3) = 113.08 in ^ 3
 answer
 the best estimate for the volume of air in the balloon in cubic inches is
 C. 113.1
