The equation of a straight line is y=mx+b, where m is the slope of the line.
By substituting the given information into this equation, we get:
7=(2/3×1)+b
Now solve to find b, the y intercept:
7=2/3+b
b=19/3
So the equation of the line is y=2/3x+19/3

C.) (5,0)
Step-by-step explanation:
You see where the lines cross together. That will be the answer.
Answer:
Thus, the value of x = -36 when y = 15
Step-by-step explanation:
We know that if y varies directly with x, we can express the relationship such as
y ∝ x
y = kx
k = y/x
where 'k' is called constant of variation.
Given
y = -5
x = 12
Using the equation
k = y/x = -5/12
Thus, the value of k = -5/12
Finding x when y = 15
y = 15
k = -5/12
substituting y = 15 and k = -5/12 in the equation
y = kx
15 = -5/12 (x)
15×12 = -5x
180 = -5x
divding both sides by -5
-5x/-5 = 180/-5
x = -36
Thus, the value of x = -36 when y = 15
