b = -0.5
4 + 2 = - 0.5 * 4 + 8
6 = -2 + 8
6 = 6
Which is true, Therefore the answer is -0.5
An irrational number has an infinite number of decimal places. It never ends.
If the decimal ever ended, then the number would be rational.
508.75/27.5= 18.5 So he pays $18.50 per square foot
And 55.5x27.5=1,526.25 that’s $1,526.25+$508.75=2035 so the total installation costs $2035.00
Answer:
(a) m= 3
(b) b= -2
(c) y=3x-2 or y=3x+(-2)
Step-by-step explanation:
(a) to find the slop you do rise over run or change in y over change in x (from point to point it goes up 3 over 1 so the slope would be 3/1 = 3)
(b) the y intercept is wherever the line intercepts (touches/crosses) the y (vertical/up and down)axis
(c) the equation formula is y=mx+b where m = the slope and b = y intercept. All you have to do is plug in the information to get your answer. You can also either add a negative or just subtract which is why there are two viable optional answers
