Answer:
Step-by-step explanation:
1.
y-intercept=-4
points: infinite points lies on it.,but one point (0,-4)
slope=3/5
2.
y-6=2(x+1)
y=2x+2+6
y=2x+8
y-intercept=8
slope=2
a point :(-1,6)
3.
y+4=2x
a point: (-2,-4) does not lie on it.
y -intercept=-4 (True)
a slope of 2 (True)
4.
y=-2/7 x
a slope of -2/7 (True)
a y-intercept of (0,0) (True)
no y-intercept (False), (0,0) is y-intercept.
5.
y+5=-(x-4)
a slope of -1
a point of (4,-5)
the answers are 5.)b 6.)c.
Answer:
WOah
Step-by-step explanation:
Answer:
1) x=3/2y+1/2
2)x=-1/3y+-5/3
Step-by-step explanation:
1)
Let's solve for x.
2x−3y=1
Step 1: Add 3y to both sides.
102x−3y+3y=1+3y
2x=3y+1
Step 2: Divide both sides by 2.
2x/2
=
3y+1/2
x=3/2y+1/2
Answer:-5/2±1/2![\sqrt{5}](https://tex.z-dn.net/?f=%5Csqrt%7B5%7D)
