Question

Write an equation for the line in point-slope and slope-intercept forms. Passes through (1, 2) and has a slope of 7. Can someone please show me how to do this?

Answer 1

Do you know what point slope form is?\[y-ycoord=slope(x-xcoord)\]

Answer 2

no

Answer 3

Passes through (1, 2) and has a slope of 7.
That's the question and I have three more like it, can you please show me how to solve it?

Answer 4

smeone please help?

Answer 5

Plug in the numbers into my point slope equation

Answer 6

wait I'm confused?

Answer 7

can you show me how?

Answer 8

point slope form is : y - y1 = m(x - x1)....
set 1 (1,2)--with x1 = 1 and y1 =2
slope (m) = 7

sub your info into the formula...
y - y1 = m(x - x1)
y - 2 = 7(x - 1) <--this is point slope form

Now you need slop intercept form...
slope intercept form is : y = mx + b
your points -- (1,2)....your slope (m) = 7
now plug in your values...
y = mx + b
2 = 7(1) + b
2 = 7 + b
2 - 7 = b
-5 = b
so your equation is : y = 7x - 5 <--slope intercept form

Answer 9

Thank you so much I think I got the hang of it!!!!!!!!!!!!!!!!!!!!!

Answer 10

thats good.....it can be confusing :)
