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
2/3 =0.66666666666 ........
K= 8. If you look at the pattern each x value is multiplied by 8 to give you the y value. You could also solve it by:
40=k5
40/5=k
8=k
you could do this with any of the x or y values and still end up with 8.
Answer:
3.5 and -3.5
Step-by-step explanation:
-3.5 in absolute value is 3.5
any negative number in I I will be positive.
Parallel lines have the same slope so for the new line we m=-2 and the point (2,2) we will substitute this info into our line to solce for b the y intercept.
Y=-2x+b
(2)=-2(2)+b
2=-4+b
2+4=-4+4+b
6=b
Now we put it all together using the slope m=-2 and the y intercept of 6
Y=-2x+6
