Answer:
y = 3x + 3
Step-by-step explanation:
Given parameters;
Coordinates of the line;
(-2, -3)
Slope of the line = 3
Unknown:
Equation of the line = ?
Solution:
The equation of any straight line is often expressed as;
y = mx + c
y and x are the coordinates
c is the intercept
Now insert values of y, x and m to find c;
-3 = 3(-2) + c
-3 = -6 + c
c = -3 + 6 = 3
The equation of the line is;
y = 3x + 3
Answer:
Tax is 9.76 total cost is 131.74
Step-by-step explanation:
40.66 x 3= 121.98
121.98 x .08= 9.76
121.98+9.76= 131.74
Answer:
Scale factor = 1.5
Step-by-step explanation:
Formula for the scale factor,
Scale factor =
In this question, image is triangle Y and preimage is triangle X.
Scale factor of X to Y =
= 1.5
Therefore, scale factor = 1.5 is the answer.
Slope = (7-3)/(5-2) = 4/3
<span>passes through the points (2,3) and (5,7).
so
y = mx + b
3 = 4/3(2) + b
3 = 8/3 + b
b = 3 - 8/3
b = 9/3 - 8/3
b = 1/3
equation
y = 4/3x + 1/3</span>
