Question

Write a rule for the linear function in the graph
(4,3) and (3,-1)


A. y = -4x + 13

B. y = -4x – 13

C. y = 4x – 13

D. y = 1/4x – 13

Answer 1

first find the slope of the line through those two points

Answer 2

Use the slope formula


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


m = (-1-3)/(3-4)


m = (-4)/(-1)


m = 4

Answer 3

now find the y-intercept

y = mx + b

y = 4x + b

3 = 4(4) + b

solve for b

Answer 4

hey

Answer 5

lemme show you how to get line equation, first u need slope of line

Answer 6

draw these 2 points of the graph if that helps you see it
