slope = 13
the slope of the tangent is f'( 4)
given f(x) = x² + 5x , then f'(x) = 2x + 5
and f'(4) = ( 2 × 4 ) + 5 = 13
Answer:
see below
Step-by-step explanation:
y = −1.5x + 3.5 is the equation of the line
Points: (5,-4), (-1,5)
Formula (y=mx+c): y = −1.5x + 3.5
Slope m: -1.5
Y-intercept b: 3.5
Parallel lines: −1.5x + any number
Perpendicular lines: 0.666666666667x + any number
