Answer:
y = (-1/2)x + 9/2
Step-by-step explanation:
the equation of a straight line can be written as;
y = mx + c ......1
Where;
m = slope
c = intercept
For two lines to be perpendicular their slope must be opposite reciprocal of each other.
m1 × m2 = -1 .....2
Given;
The equation Contains (3, 3); and perpendicular to the line y = 2x - 1
Slope of the given equation m1 = 2
Slope of the line m2; substituting m1 to equation 2.
2 × m2 = -1
m2 = -1/2
So,
y = (-1/2)x + c
To solve for c, let's substitute the given point on the line; (3,3).
3 = (-1/2)(3) + c
3 = -3/2 + c
c = 3 + 3/2
c = 9/2
Therefore, the equation of the line that has the given properties is;
y = (-1/2)x + 9/2
Answer:
-2x2 y1/3
Step-by-step explanation:
Step-by-step explanation:
Equation of straight line: y=mx+b
Given slope=2, hence m=2
y=2x+b
Replace y and x values as stated in the question (-1, -2)
(-2)=2(-1)+b
-2+2=b
b=0
rewrite the equation:
y=2x+0
y=2x
For 3) a solid line is used when the equation is <= or => while dotted line is for when the equation is < or >
Could you elaborate on question 2? I dont quite get what the question is asking for
