Answer:
1) 3x+4y=8
4y=-3x+8
4y/4=-3x/4+8/4
y=-3/4x+2
slope=-3/4
Y intercept=2
2) 9x+35=-5y
-5y/-5=9x/-5+35/-5
y=-9/5x-7
slope=-9/5
y intercept=-7
3)2y-6=-6x
2y−6+6=−6x+6
2y /2−6x/2+6 /2
y=−3x+3
slope is -3x
y intercept is 3
1. -0.6
2. 0.65
3. 2/3
4. 4/5
Step-by-step explanation:
55km(per hour)
440km(8hours)
