Answer:
The equation is y = -5x + 55
Slope = -5
y-intercept = 55
Step-by-step explanation:
The given table shows the different coordinates of points on a straight line.
The general equation of a line is y = mx + b
where m is the slope and b is the y intercept.
Actually , here only 2 values are needed but there are 4 values given which is just to check whether our line is correct or not.
Substitute values of x and y in the equation.
Put (1,50),
50 = m + b ----------(1)
Put (2,45),
45 = 2m + b -----------(2)
Solve (1) and (2),
Slope , m = -5
y-intercept , b = 55
Hence , the equation is y = -5x + 55.
Answer:

Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
m∠A + m∠B = m∠B + m∠C
Use the subtraction property of equality to subtract m<B from both sides of the equation.
m∠A + m∠B - m<B = m∠B - m<B + m∠C
m∠A = m∠C
