Answer:
1 hour and 42 min
Step-by-step explanation:
Slope-intercept form is y = mx + b, and m is the slope
Because the slope is -3, m = -3
y = -3x + b
Plug in the point and solve for b
-7 = -3(-3) + b
-7 = 9 + b
-16 = b
a. y = -3x -16
The equation of this line is y - (-3) = (1/2)( x - 6 ), <span>which is equivalent to y + 3</span> = (1/2)( x - 6 );
Put the value of x = 4 to the expression 3x + 2.
(3)(4) + 2
<em>first multiplication and next addition</em>
= 12 + 2 = 14
