Question

PLEASE I NEED HELP !!

question: Find the values of k and b if it is known that the graph of y=kx+b goes through points (2, 10) and (−7, −10).
what is k and what is b
PLEASEEEEE

Answer 1

k = 20/9

b = 50/9

Explanation:

slope intercept form: y = mx + b

given equation: y = kx + b

(-10-10)/(-7-2)

= 20/9

10= 2 x 20/9 + b

90 = 40 + b

b = 50

y = 20x/9 + 50
