u should try then give me your answer
what do you think about that?

anonymous · Answer

i got y = 15x + -144

anonymous · Answer

y-15      =9
-----
x-9
y-15=9(x-9)
y-15=9x-81
y=9x-66 

it cant be 15x since your gradient is 9 therefore its 9x

what about this The slope of a line is 13 and the point (3, 19) is on the line. Express the line in slope-intercept form.

anonymous · Answer

you already know that x is 13 thus 13x
y-19      = 13
----
x-3
y-19=13(x-3)

y-19=13x-39

y=13x-20
