Question

Is this correct? equation of line

Answer 1

question: Write the equation of a line in slope-intercept form passing through (3, 5) and (2, 9)

my answer:
finding slope:

m = (5 - 9)/(3 - 2)

m = -4/1

m = -4

finding y-intercept:

y = mx + b

5 = -4(3) + b

5 = -12 + b

5 + 12 = -12 + b + 12

17 = b



equation: y = -4x + 17

Answer 2

so i think this is right,correct

Answer 3

but i know thge standard form y = mx +c not b

Answer 4

the standard form

Answer 5

yes its correct

Answer 6

Thanks!
