Question

What is the slope-intercept form of the function that contains the points (3, 1) and (2, 9)?

y = x +

Answer 1

medal and fan

Answer 2

y2-y1
-----
x2-x1 is slope. can you fill that in?

Answer 3

?

Answer 4

slope would be 9-1
-----
2-3

Answer 5

ohh i get u now.

Answer 6

m = (y2 - y1)/(x2 - x1).
m = (9 - 1)/(2 - 3).
m = 8/-1 = - 8.
Therefore slope, m = -8.

Using y = mx + c. Slope = m, m = -8.
y = -8x + c

Substituting any of the point (3,1) into the equation, x = 3, y = 1.
1 = -8(3) + c
1 = -24 + c
1+24 = c
25 = c
c = 25 Substituting into y = mx + c, m =-8, c = 25
Therefore y = -8x + 25.
y = -8x + 25.
