The answers are following
sol1 y = x-1
sol2 y= x+ 7
sol4 y = x+4
Step-by-step explanation:
Solution 1
Here we are going put the point in the given equation ( given in the options)
If the each point satisfies any equation, that will be the relationship between x and y.
Given points are (-3,-4) , (2,1) , (5,4)
Let us take the option C as y = x -1
-4 = -3-1
1 = 2-1
4=5-1
Putting each value in the given equation we get LHS and RHS are same for all points. so, C is the answer.
Similarly, option B is the answer of Solution 2
Each point satisfies the equation y = x +7
Solution 4
y = x +4
You are requested to check the options of Q3 once.
Segment WT and DG are congruent which means that the shape and size, but we are allowed to flip, slide or turn. In this example the shapes are congruent (you only need to flip one over and move it a little). Angles are congruent when they are the same size (in degrees or radians). Sides are congruent when they are the same length.
