Find the value of x so that the line passing through (10, 5) and (x, 9) has a slope of -2.

Question

anonymous · Answer

Use The Law :
$$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=m$$
Where m=slope and (10,5)=(x1,y1) ....(x,9)=(x2,y2)
Now fill up the Rule,and solve it ..

Find the value of y so that so that the line passing through (4, y) and (5, 3) has a slope of 1.
 on this one what do i do after i get 4/4 ?

anonymous · Answer

Since the x value increased by one, you need to make the y value increase by 1 in order to have a slope of 1. Therefore, you need to find a number that equals 3 when added to 1, which is 2.
