Factor by grouping is (3x+5)(x+5) .
Answer:
b. The slope of the line
Step-by-step explanation:
To explain the question statement, first we view the pattern of regression of equation which is
Y=a+bx
Where Y is dependent variable and x is an independent variable.
a represents the Y-intercept and depicts the value of dependent variable y when independent variable x=0. b represents the slope in the regression equation and interpreted as unit change in dependent variable Y due to unit change in independent variable X.
7 + (-3x^2) for x = 0 7 + [-3(0)^2]; = 7 + -3(0); = 7 - 0; = 7
