Answer:

Option D is correct

The point slope intercept equation of line = $y-9=2(x-1)$

Step-by-step explanation:

Given: The slope of line (m) = 2 and also it is given from the figure the

Point-slope intercept form: If we have a point $(x_1, y_1)$ and a slope, m, then the formula

we use to find the equation of a line:

$y-y_1=m(x-x_1)$ .......[1]

Substitute the value of m =2 and (1, 9) in [1];

$y-9=2(x-1)$

Therefore, the point slope intercept equation of the line is: $y-9=2(x-1)$

142 is 120% of what number

forsale [732]

142=120% of x
120% of x= 1.2x
142=1.2x
142/1.2 = 1.2x/1.2
x= 118.33

The unknown number should be 118.33, rounded to 118 or so.
