The equation in slope-intercept form of the line that passes through the point (-1, 2) and is perpendicular to the line equation,
is: 
<em><u>Recall</u></em>:
Equation of a line in slope-intercept form is:
, where, slope = m, and y-intercept = c.
Point-slope form is: 
The slope value of a line will be the negative reciprocal of the slope of the line it is perpendicular to. i.e. if the slope of a line is a, the slope of the line that it is perpendicular to will be -a.
<em><u>Given:</u></em>
- The line passes through point (-1, 2)
- Equation of line it is perpendicular to is:

To write the equation of the line that passes through (-1, 2), we need to find the slope value.
- First, rewrite
and find its slope.

- The slope (m) of
is therefore 1.
- Thus, the slope (m) of the line that passes through (-1, 2) will be the negative reciprocal of 1 = -1.
- Write the equation of the line by substituting (a, b) = (-1, 2) and m = -1 into
:

- Rewrite this in the form of


Therefore, the equation in slope-intercept form of the line that passes through the point (-1, 2) and is perpendicular to the line equation,
is

2544 because 2400x.03 x2 equals 144 2400 +144= 2544
The answer to 31,096 + 59,721 is 89,817 so B 89,800 is the best estimate
2nd- The answer to 69,896 - 42,901 is 26,995 so A 26,900 is the best answer
3rd- 630,429 - 27,811 is 602,618 so the best answer(s) would be A 630,400 and C 27,800
