Question

Find the equation of the line through (-4,0) and (0,2). Give it in slope-intercept form.

Answer 1

first, find the slope of the line through (-4,0) and (0,2) using the slope formula:
\(\large m=\frac{y_2-y_1}{x_2-x_1}= \) ????
what's the slope?

Answer 2

It doesn't give me the slope

Answer 3

1/2

Answer 4

use the coordinates of the given points to calculate the slope...

Answer 5

ok... slope is 1/2. Do you the y-intercept?

Answer 6

*know

Answer 7

look carefully at the points given to you...

Answer 8

2?

Answer 9

correct...

Answer 10

a line in slope-intercept form is given as: \(\large y=mx + b \)
where m is your slope and b is your y-intercept. all you need to do now is replace the the values you found into that equation.

Answer 11

So it's y=1/2x+2?

Answer 12

yes... u got it.... :)

Answer 13

Thank you! :DD
