Question

Please help! Same is reading Harry Potter and the chamber of secrets. He is currently on page 19. After reading for 40 minutes he is on page 339.
Slope:
Y-intercept:
Equation:

Answer 1

Answer:

y = 8x + 19

Step-by-step explanation:

Slope:

• $\frac{339-19}{40-0}$
• $\frac{320}{40}$
• $8$

Slope: 8

Y-intercept:

Input points

• $339 = 8(40) + b$
• $339 = 320 + b$
• $b = 19$

Y-intercept: 19

Equation:

y = 8x + 19

Answer 2

Here the co-ordinates are

• (0,19)
• (40,339)

Slope:-

$\\ \tt\hookrightarrow m=\dfrac{339-19}{40-0}=\dfrac{320}{40}=8$

Equation of line in point slope form

$\\ \tt\hookrightarrow y-y1=m(x-x_1)$

$\\ \tt\hookrightarrow y-19=8(x)$

$\\ \tt\hookrightarrow y-19=8x$

• Convert to slope intercept form y=mx+b

$\\ \tt\hookrightarrow y=8x+19$

• y intercept=b=19
