Answer:
m = 2/3
b = -3
Step-by-step explanation:
Rearrange the equation to slope-intercept form (y = mx + b).
x and y are points on the graph.
m is the slope.
b is the y-intercept.
Isolate "y". This means separating it from the other numbers.
-2x +3y = -9
-2x + 2x +3y = -9 + 2x Add 2x to both sides
3y = 2x - 9
3y/3 = 2x/3 - 9/3 Divide both sides by 3
y = 2x/3 - 9/3 Simplify
y = (2/3)x - 3
Think about which numbers and "m" and "b" now that the equation is in y = mx + b. Include the plus and minus signs.
m = 2/3
b = -3
Divide 5/8 by 150, to see how thick each is, that'll give you 150 even pieces that add up to 5/8
Answer 17: -6/25-29%-3/10-1/3-34.5%-
Explanation: 6/25 is .24 as a decimal, 29 is .29, 3/10 is .30, 1/3 is .33, and 34.5 is .34
Answer 18: 78% is the same as 7.8/10 not 7/8. 7/8 as a percent is 87.5%
Answer: (a) x + 2y = -1 and 3x + y = 1
