7<br> Write an equation of a line<br> with slope of 23 and<br> y-intercept -6.
emmainna [20.7K]

Answer:

y = 23x - 6

Step-by-step explanation:

The formula for line is y =  mx + b

m is the slope, so plug in 23

b is the y intercept, so plug in -6

So it would be y = 23x + (-6), which simpify into y = 23x - 6

Solve 7y-6=2y+8 show clear algebraic working
aniked [119]
1) subtract 2y in both sides: (7y-2y)-6=(2y-2y)+8 which is 5y-6=8
2) Add 6 to both sides: 5y(-6+6)=8+6 which is 5y=14
3) Divide 5 on both sides: 5y/5=14/5 which is y=14/5 or y=2.8 or y=2 4/5

Given the expression:

2.5( \frac{8.6}{2} ) - 1.8

2.5( \frac{8.6}{2} ) - 1.8 \\  = 2.5(4.3) - 1.8 \\  = 10.75 - 1.8 \\  = 8.95
