slope intercept form is y = mx + b where m is the slope and b is y-intercept right?

3. emily9102

yea @ money

4. moneybird

$m = \frac{y_2-y_1}{x_2-x_1}$ where points (x1, y1) and (x2, y2) are on the line

5. emily9102

yes

6. Jusaquikie

$m=\frac{ y _{2}-y _{1} }{x _{2}-x _{1} }$ or $m=\frac{ 20-4 }{4-0 }$

7. moneybird

so (4, 20) and (0, 4) are the points can you find the slope with the formula

8. emily9102

15/4

9. emily9102

4**

10. Jusaquikie

so the slope is 4 and you put that in the equation

11. moneybird

y -intercept occurs when x = 0

12. emily9102

y=4x+b

13. moneybird

when x = 0, what does y = to?

14. emily9102

hmm y=b? 0.o

15. emily9102

sorry getting a little confused

16. moneybird

(0,4) when x = 0, what does y equal to?

17. emily9102

4

18. emily9102

._. right?

19. emily9102

@moneybird ?
