Question

write an equation in slope intercept form of the line through point P(6,7) with slope -2

Answer 1

the formula of the slope is
\[\large m=\frac{y_1-y_2}{x_1-x_2} \]
u have m=-2 and (x1,y1)=(6,7). replace and do the algebra

Answer 2

i just need to know the formula, i am still a little confused, can you explain it a little more? :)

Answer 3

we have
\[\large -2=\frac{7-y}{6-x} \]
now do the algebra

Answer 4

so is it y-7=-2(x-6) ?

Answer 5

yes but u have to do some algebra
\[\large y-7=-2(x-6)=-2x+12 \]
\[\large y=-2x+19 \]
which is in the slope-intercept form

Answer 6

oh thank you!
