Question

The slope of a line is 9 and the point (9, 15) is on the line. Express the line in slope-intercept form.

Answer 1

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

Answer 2

i got y = 15x + -144

Answer 3

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

Answer 4

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.

Answer 5

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
