What is the slope of the line represented by the equation 4x+3y=12

Answers

Answer 1

Answer: To do this we need to rewrite the equation in terms of y
4y=12-3x
y=3-3x/4
Therefore the gradient is -3/4

-l0 = -2+1/2 d solved for d

Answers

$-10 =-2+ (1)/(2) d$

$-10=-2+ (d)/(2)$

$-10= (d)/(2) -2$ $Regroup \ terms$

$-10+2= (d)/(2)$ $Add \ 2 \ to \ both \ sides$

$-8= (d)/(2)$

$-8*2=d$ $Multiply \ both \ sides \ by \ 2$

$d=-16$
