Alejandro made an error in the steps below when determining the equation of the line that is perpendicular to the line 4x – 3y = –8 and passes through the point (3, –2). alejandro made his first error in which step? a. step 1 b. step 2 c. step 3 d. step 4

This is the concept of equations of graphs; We are required to calculate for the equation if the line that is perpendicular to the line 4x-3y=-8 and passes through point (3,-2).
Here we proceed as follows;
4x-3y=-8 can be written in he form y=mx+c as follows;
-3y=-4x-8
thus;
y=4/3x+8/3
The slope of the line perpendicular to this is -3/4. Thus using p[oint (3,-2) the equation will be as follows;
-3/4=(y--2)/(x-3)
-3/4(x-3)=y+2
y+2=-3/4(x-3)
y+2=-3/4x+9/4
thus;
y=-3/4x+1/4
the answer is:
y=-3/4x+1/4

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
