Find the slope‐intercept form of the equation of the line for each slope, m, and each y‐intercept, b.
1. m = 7, b = ‐4
2. m = 0, b = 0
3. m = ‐5, b = 2
4. m = 0, b = ‐1
5. m = 4.6, b = ‐2.9
6. m = 7/8, b = ‐4

State the slope and y‐intercept of the graph of each equation.
7. y = ‐4x +3
8. y = 7x – 6
9. y = 1/8x – 2
10. ½ y = x – 5
11. –y = 0.3x + 7
12. ‐2y = ‐x

State the slope‐intercept form of each equation.
13. 9x + 5y = ‐3
14. 4x = 7
15. x – 3y = 8
16. ‐5x + 2y = 14
17. 6.2x – 3.1y = 9.3
18. 1/7 x – 1/6 y = 1/9

Find the slope‐intercept form and the standard form of the equation of the line that satisfies the given
conditions.
19. Slope = ‐2/3, passes through (6, 1)
20. Slope = 5, passes through (‐4, 7)
21. Slope = ‐8, passes through the origin
22. Passes through (2, 4) and (‐7, 2)
23. X‐intercept = 0, y‐intercept = ‐5
24. X‐intercept = ‐4, y‐intercept = 0

Sagot :

Slope intercept form is y=mx+b m=slope, b=y-intercept

13-18 Solve the equations so that y is by itself.

19-21 Plug in the slope, and plug in the points for x and y, then solve for b.

22 Find the slope, then plug in the points for x and y, and solve for b.

23 There is no slope, so it is just y=-5

24 Slope is zero, so it is just x=-4
