Answer:
y=3x+5
Or option A
Step-by-step explanation:
Answer:
x=17
Step-by-step explanation:
24-3x=-27
1) Subtract 24 from both sides:
-3x=-51
2) Divide both sides by -3:
x=17
Footnotes:
Don't forget, your goal is to <em>isolate</em> the variable, or get it on one side of the equation
4y-17=43
move -17 to the other side
sign changes from -17 to +17
4y-17+17=43+17
4y=43+17
4y=60
divide both sides by 4 to get y by itself
4y/4=60/4
answer:
y=15
To find the slope, you find the change in y-values over the change in x-values.
Your first point is: (5,-3)
Your second point is (8, -5)
Your x-values are: 5 and 8
Your y-values are -3 and -5
The equation to find slope is: slope = (y2-y1)/(x2-x1)
- The 2s and 1s indicate which point the values belong to, it makes sure that you align the right x-value with its correct y-value. It doesn't matter which point you assign as 1 or 2, as long as the values match
- So, x-value 5 will match with y-value -3, and x-value 8 will match with y-value -5
Now you plug in out values :
slope = (y2-y1)/(x2-x1)
slope = (-5-(-3))/(8-5)
slope = (-2)/(3)
slope = -2/3
