Point slope form of (3, -3), (1,-7)

Step-by-step explanation:

-7- -3= -4

1- 3= -2 -4/-2=2

you can use either points

y-y1=m(x-x1)

if the point is negative then the sign changes to a plus

y+7= 2(x-1)

aka y+7 =2x-2

(^that would be -2 because you do 2x-1 bc you have to distribute when you solve )

Y = -2x + 3

Step-by-step Explanation:

Y = mx + b

Slope = -2, so we need to solve for b

Y = -2x + b

Use one of the two points given to solve for b

-3 = -2(3) + b

-3 = -6 + b

3 = b

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
