Question

need help, use the formula y=mx=b find the equation of the line determined by the two points (9,4) and (7,2) y = _____x +_____

Answer 1

you have to find the slope first using this formula y2-y1/x2-x1

then use one of those points above and plug it into the x and y values and solve for b

Answer 2

y=mx+b

Answer 3

y2-y1/x2-x1=m

Answer 4

4-2/7-9=1

Answer 5

y-yinitial= m(x-xiniital)

Answer 6

y-4=1(x-4)

Answer 7

y-4=x-4

Answer 8

y=x

Answer 9

is your answer

Answer 10

sorry i meant 9 y-4=x-9

Answer 11

y=x-5

Answer 12

:)

Answer 13

ok so it would read y=1x + -5
