Answer: m = 7 or -2
Step-by-step explanation:
Quadratic Formula!
Polynomial Form:
So in this example a: 1 b: -5 c: -14
You get:
m = 7 or -2
Check by plugging a value back in for m
True for both.
ANSWER:
[a] A linear regression line has an equation of the form Y = a + bX, where X is the explanatory variable and Y is the dependent variable. The slope of the line is b, and a is the intercept (the value of y when x = 0).
[b] In the equation of a straight line (when the equation is written as “y = mx + b”), the slope is the number “m” that is multiplied on the x, and “b” is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the “Slope-intercepts form”.
