Answer:
b
Step-by-step explanation:
+2
slope of line(m) = 2 and intercept on y axis is -2 that is 2 unit in negative y axis.
Equation of line in slope intercept form:
Slope:
Slope is known as tangent of an angle made by positive X-axis.
We know equation of line in slope and intercept form is,
y = mx + b
where,
m is slope of line
b is intercept on y axis
hence for the given equation,
y =2x - 3
slope (m) will be = 2
intercept on y axis (b) = -3
thus,
option (B) will be correct.

Answer: d = 1/5t
Step-by-step explanation:
Since it is a direct variation , Let d represent the distance and t represent the time ,then
d ∝ t
introducing the proportionality constant, we have
d = kt
Substituting t = 10 and d = 2 , we have
2 = 10k
k = 1/5
substitute k = 1/5 into the original equation , we have
d = 1/5t
100%/x%=32.2/24.15
<span>(100/x)*x=(32.2/24.15)*x - </span>we multiply both sides of the equation by x
<span>100=1.33333333333*x - </span>we divide both sides of the equation by (1.33333333333) to get x
<span>100/1.33333333333=x </span>
<span>75=x </span>
x=75
<span>now we have: </span>
<span>24.15 is 75% of 32.2</span>
