If (-2,11)and(9,22) are two anchor points on the trend line, then find the equation of the line

Elza [17]

Answer:

The equation of the line is $y=x+13$

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

(-2,11) and (9,22)

substitute

$m=\frac{22-11}{9+2}$

$m=\frac{11}{11}$

$m=1$

step 2

Find the equation in slope intercept form

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=1$

$point\ (-2,11)$

substitute in the equation and solve for b

$11=(1)(-2)+b$

$11=-2+b$

Adds 2 both sides

$b=11+2\\b=13$

The equation of the line is

$y=x+13$

What value of x is n the solution set of 2x-3>11-5x

mario62 [17]

The value of x if that's what you mean is 2 because first you add 3 from both sides and your new equation should be 2x>14-5×, then you add 5x from both sides and your new equation should be 7x>14. After that you divide 14 by 7 and your final answer will be x=2 or 2

Mary and her brother John

BabaBlast [244]

let, x be the no of coins then according to question.Mary have 3x no of coins and John have x no of coins..

now, 3x+x=180

or,4x=180

or,x=180/4

therefore, x= 45

thus mary has 3×45=135 no of coins...
