Question

Find the slope and the y-intercept of the equation y − 3(x − 1) = 0.
slope= -3 and y-intercept -3
slope= 3 and y-intercept 3
slope= -3 and y-intercept 3
slope= 3 and y-intercept -3

Answer 1

arrange it into\[y=mx+c\]

Answer 2

where\[y=vertical~axis\]\[x=horizontal~axis\]\[m=slope\]\[c=y-intercept\]

Answer 3

\[y\color{red}{-3(x-1)}=0\]First expand the left side

Answer 4

\[y-3x+3=0\]Then,add both sides by 3x

Answer 5

\[y-3x+\color{red}{3x}+3=\color{red}{3x}\]

Answer 6

\[y+3=3x\]

Answer 7

Then,subtract 3 on both sides

Answer 8

\[y+3\color{red}{-3}=3x\color{red}{-3}\]

Answer 9

\[y=3x-3\]

Answer 10

now try comparing with\[y=mx+c\]where\[y=vertical~axis\]\[x=horizontal~axis\]\[m=slope\]\[c=y-intercept\]

Answer 11

to find the slope and the y-intercept
