Question

MEDAL + FAN FOR RIGHT ANSWER!!!!

Portia drew a line on the coordinate plane that passed through the points (-3,19) and (2,9). Which equation represents the line that Portia drew?

Answer 1

y=mx+b
m=slope
b=y-intercept

Answer 2

slope = \[\frac{y2-y1}{x2-x1}\]

Answer 3

A. y = -2x + 13
B. y = -1/2x + 7
C. y = -1/2x + 13
D. y = -2x + 7

Answer 4

id say b

Answer 5

y-y1=m(x-x1) is a line with slope m that passes through the point (x1,y1)
you can rearrange this to be
y=mx-mx1+y1
so
b=-mx1+y1

Answer 6

y=-2x+13

Answer 7

i meant a

Answer 8

got them confused

Answer 9

thanks guys
