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

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

39 cm

Step-by-step explanation:

using the x component go find 12 cm width and follow the line up until it intersects the graph. then follow that point left to estimate the height at that point to estimate 37.5 but more accurately you can use the given equation y=3.25x and plug in your x of 12 to get y=39
