Answer:
Step-by-step explanation:
y and x are the point while 'm' is the slope and 'c' is the intercept
or using calculus
differentiating y with respect to x
dy/dx=m
which is the required slope
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
Answer: is it 8
Step-by-step explanation: i just guess the middle number
y= -1/2
x=3/2
first isolate x
2x+4y=1
2x=1-4y
x=(1-4y)/2
subsitute it in the second equation
look at the pic
9.2
Use law of sines
a/sinA = b/sinB
5/sin 31 = b/sin 108
b=9.2
