Answer:
1.y=2x+7
2.y=1/2x+2
Step-by-step explanation:
Graph 1-
The slope-intercept form is y=mx+b
b= y-intercept which in graph 1 is 7
so y=mx+7
in order to find m you use the y2-y1/x2-x1 equation.
This means find two coordinates on the graph such as (0,7) and (-1,5).
Now find y2:5
y1:7
x2:-1
x1:0
y2-y1= 5-7=-2
x2-x1= -1
That gives you -2/-1 which you then simplify to = 2
So the graph would be y=2x+7
Graph 2:
You will do the same steps: Find where the line passes through y on a graph, which will be y=2.
b=2
y=mx+2
then find two coordinates, (0,2)(2,3)
y2=3
y1=2
x2=2
x1=0
y2-y1=3-2=1
x2-x1=2-0=2
The slope of the graph which is m= 1/2
y=1/2x+2
-23 we just had to do that exact problem in math
Answer:
$27.98
Step-by-step explanation:
100 - 30 in price %=70%
Price will be 70% of original regular price
$39.98 * .7 = answer
Answer:
Step-by-step explanation:
Lets start with 13
-2(13 + 3) = -4(13) + 20
-32 = -52 + 20
-32 = -32
x = 1 basically
now 19
-2(19 + 3) = -4(19) +20
-44 = -76 + 20
-44 = -56
so divide those
-2(31 + 3) = -4(31) + 20
-68 = -124 + 20
-68 = -104
divide them
-2(37 + 3) = -4(37) + 20
-80 = -148 + 20
-80 = -128
