state the y-intercept and the slope of the following linear equations.
Answer:
think of y=mx+b
m is the slope
b is the y-intercept
1) y=3/4x-2
slope= 3/4
y-intercept= -2
2) y= -x+3
slope= -x
y-intercept= 3
3) y=3x+5
slope=3
y-intercept=5
4) y=1/2x-5
slope= 1/2
y-intercept= -5
5) y= -2x-4
slope= -2
y-intercept= -4
6) y= -1/5x-1
slope= -1/5
y-intercept= -1
7) y=3/2x+4
slope=3/2
y-intercept=4
8) y=x+1
slope=x
y-intercept=1
9) y=2x+5
slope=2
y-intercept=5
10) y=8/5x+3
slope=8/5
y-intercept=3
11) y= -3x-4
slope= -3
y-intercept= -4
12) y= -2x-2
slope= -2
y-intercept= -2
Answer:
P = -4
Step-by-step explanation:
Assuming that x = 20 and y = 24, you have to plug in these numbers for x and y to get to this equation P = 20 - 24. You should get -4 when you subtract 24 from 20 giving you a negative answer.
It would be helpful if you could post a photo so I can look at the context. Thank you
Consider, please, the suggested option.
Note, that the answers are marked by red.
14/x = 1/2
Cross multiply, which is: a/b = c/d ⇒ ad = bc
After cross multiplying, we get:
x = 2(14)
x = 28
Your final answer is C. 28<span>.</span>
