Question

Using the linear equation, y = mx +b and solve for B (7,1)(-12,-6)

Answer 1

Answer:

Step-by-step explanation:

first we need to find the slope bu using the slope formula and ur two sets of points

slope = (y2 - y1) / (x2 - x1)

(7,1)...x1 = 7 and y1 = 1

(-12,-6)....x2 = -12 and y2 = -6

now we sub

slope = (-6 - 1) / (-12 - 7) = -7/-19 = 7/19

now...in y = mx + b form, the slope will be in them position

y = mx + b

slope(m) = 7/19

use either of ur points.....(7,1)...x = 7 and y = 1

now we sub and find b, the y int

1 = 7/19(7) + b

1 = 49/19 + b

1 - 49/19 = b

19/19 - 49/19 = b

- 30/19 = b <======= ur y int

so ur equation is : y = 7/19x - 30/19
