-21 = a - 2(8) because the graph passes through (8,
-21)
a = -21 + 16 = -5 answer
Not sure how to do it in this form but in slope intercept form for example if the slope was -4/3 the perpendicular would be 3/4 it’s the negative reciprocal of the answer
Hello ;
<span>A line contains the point (0,0) : y=ax a is aslope
a = (yb -yO)/(xb -xO) B(1;4) O(0;0)
a = (4-0)/(1-0)=4
</span><span>all the equations that represent this line is : y = 4x or y-4x = 0</span>
(1+0.30)=1.30
56 (1.3) = 72.80
The price of the pair jeans before the sale was $72.80
