Answer:

The slope-intercept form of the function is:

y=5x+3

Step-by-step explanation:

Given the table

x                      y

1                      8

2                     13

3                     18

4                     23

Let us take two points (1, 8) and (2, 13) to find the slope

  • (1, 8)
  • (2, 13)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(1,\:8\right),\:\left(x_2,\:y_2\right)=\left(2,\:13\right)

m=\frac{13-8}{2-1}

m=5

We know that the slope-intercept form of the line equation is

y=mx+b

where m is the slope and b is the y-intercept.

substituting the values m=5 and the point (1, 8) to determine the y-intercept i.e. 'b'.

y=mx+b

8 = 5(1) + b

b = 8-5

b = 3

Now, substituting the values m=5 and b=3 in the slope-intercept form to

y=mx+b

y=5x+3

Thus, the slope-intercept form of the function is:

y=5x+3

nika2105 [10]

Answer:

H=13cm

Step-by-step explanation:

Volume= Length x Width x Height

v=624cm^3

L=8cm

W=6cm

8cm x 6cm=48cm^2

Divide 624cm^3 by 48cm^2= 13cm

H=13cm

Hope this helps!
