Answer:
y = -1
+ 1
Step-by-step explanation:
The line (a) passing through point (3, -4) is perpendicular to line (b) whose equation is; y = -2 + 
x
The slope of line (b) =
For perpendicular lines, the product of their slopes = -1
So line (a) has a slope of: -1 ÷ = -
Taking another point (x,y) on line (a);
Slope = change in y ÷ change in x
= -
y + 4 = (x - 3)
y = -x + 5 - 4
y = -x + 1
Finally,
y = -1 + 1
Answer:
-4
Step-by-step explanation:
Use slope intercept form: 
= 
= -4
The first step for solving this expression is to write the division as a fraction.
× m³
Factor out 2 from the numerator (top) of the fraction.
× m³
Reduce the fraction with 2.
(-2
+
- 7
)m³
Lastly,, distribute m³ through the parenthesis to get your final answer.
-2
+
- 7

Answer:
The original rectangle had a width of 30 m and a length of 150 m.
Step-by-step explanation:
Answer:
y = 10x-37
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = 10x+b
Substitute the point into the equation
3 = 10*4+b
3 = 40+b
Subtract 40
3-40 = 40+b-40
-37 = b
y = 10x-37
