Question

What equation in slope intercept form represents the line that passes through the two points? (6.9, 5.9), (10.9, -2.1) Please and thank you everyone

Answer 1

use the slope formula
\[\huge \frac{ y_2-y_1 }{ x_2-x_1 }\]

Answer 2

Can you show me step by step on how to do that?

Answer 3

to get your slope,
from there input
one of the coordinate pairs of (x,y) and your slope (m)
into
y = mx +b
and solve for b
after that you have all yours values for slope-intercept

Answer 4

\[\huge \frac{ -2.1-5.9 }{ 10.9-6.9 } = \frac{ -8 }{ 4 } = -2\]

Answer 5

\[\huge y = mx + b\]
let's use (6.9,5.9)
\[\huge 5.9 = 2(6.9) + b\]
\[\huge 5.9 = 13.8 + b\]
\[\huge -7.9 = b\]

Answer 6

\[\huge y = 2x - 7.9\]

Answer 7

Thank you for the steps. This has been difficult to understand for me. Thank you again.
