Lostsunrise [7]

Answer:

answered

Step-by-step explanation:

A) there y- coordinates are same . This means that the points lie on the x- axis only.

b) since the y- coordinate is zero of  both the points. The distance between them must be same as the distance between their x- coordinates. Which can be easily obtained with help of the number line. Here the distance will be equal to 9 units.

c) since the y- coordinate is zero of  both the points. The distance between them must be same as the distance between their x- coordinates. Which can be easily obtained with help of the number line. Here the distance will be equal to 9 units

What value of b will make the point {3,-1} lie on the line y=mx-7 in standard {x,y} coordinate plane?
kicyunya [14]

Answer:

m=2

Step-by-step explanation:

We are given a line y=mx-7 and the point lying on the given line is (3,-1) in the standard {x,y} coordinate plane.

Therefore, substituting the values of x=3 and y=-1 in the given line, we have,

⇒y=mx-7

⇒(-1)=m(3)-7

⇒-1+7=3m

⇒6=3m

⇒m=2

Hence,the value of m will be equal to two.
