Y=mx+b where m=slope=(dy/dx) and b=y-intercept (value of y when x=0)
You have two points...(1,-2),(3,2) so
m=(y2-y1)/(x2-x1)=(2--2)/(3-1)
m=4/2=2 now that you have the slope...
y=2x+b, you can use either point to solve for the y-intercept, I'll use (3,2)
2=2(3)+b
2=6+b
b=-4 so the line is:
y=2x-4
Answer:
~47%
Step-by-step explanation:
18 / 38 = 0.47368421053 = ~0.47 = 47%
We can use the points (7, 4) and (5, 6) to solve.
Slope formula: y2-y1/x2-x1
= 6-4/5-7
= 2/-2
= -1
