A. cause i did it on the calculator so i know its right
6.
the y-intercept is 4, which means the line crosses the y-axis at the point (0,4).
[just put a dot on the number four that's right under the letter y]
the slope of the line is positive, so it goes up from left to right.
Start at the y-intercept. Move up 2 and then move right 1.
You are now at the point (1,6).
[go to 1 for the horizontal line, then go up 6 spaces.] [connect two points]
7. y= -1/2-3
8. y=3x+4
Hello! There is a markup, so the price goes up. We add 1 to the percentage rate in decimal form, then we multiply that by the original price to go straight to the new price. 45% in decimal form is 0.45. 1 + 0.45 is 1.45. 25 * 1.45 is 36.25. There. The new price of the jeans is $36.25.
2(n+3)= 4
n= -1
-1+3=2 then 2x2=4. Sum is an answer to an addition problem so a number and 3 times 2 = 4. Hope this helps and have a great day!
