Answer:
y= -1/2 + 1
Step-by-step explanation:
It starts at +1 which is the B in y=mx+b. B is where a point touches the y-axis.
starting at a point: (-2,2), it goes down 1, and right 2. which now the slope is -1/2 because it is going down.

Answer:
5x -3y + 11 = 0 .
Step-by-step explanation:
Firstly let's find the slope of the line by converting the equation into slope intercept form as ,
=> 3x +5y = 7
=> 5y = 7 - 3x
=> y = (7-3x)/5
=> y = -3/5x + 7/5
- On comparing this equation to the slope intercept form y = mx + c ,
=> m = -⅗
Now the slope of the line perpendicular to this line will be , say m'
=> m' =- 1/m
=> m' = -1/-⅗
=> m = 5/3
- Now the line passes through (-1,2 ) . so on using point slope form , we get ,
=> ( x - x1) m = ( y - y1)
=> ( x - (-1)) × 5/3 = y - 2
=> ( x +1)×5 = 3( y -2)
=> 5x + 5 = 3y -6
=> 5x - 3y +5 +6=0
=> 5x -3y +11 = 0
<h3>
• Hence the equation of line perpendicular to the given line is <u>5</u><u>x</u><u> </u><u>-3y </u><u>+</u><u> </u><u>1</u><u>1</u><u> </u><u>=</u><u> </u><u>0</u><u> </u><u>.</u></h3>
