"+-" should always be changed to "-".

You have 3 - 7 - 2. You may evaluate this from left to right, obtaining -4 -2, or -6.

4 - 16 -2(2) involves multiplication, which must be carried out before addition or subtraction. Thus, 4 - 16 - 4. Working from left to right, we get -12 - 4 = -16

Find an equation of a line through (2, 1) and perpendicular to −2x + 4y = 8

MAVERICK [17]

Hello:
the equation is : y = ax+b
the slope is a : a×(1/2) = -1......( perpendicular to a line with a slope of 1/2) because : -2x+4y =8...y=(1/2)x+2 )

a = -2 y=(-2x+b
the line that passes through (2,1) :1 = -2(2)+b
b =5
 the equation is : y = -2x+5
