Intercepts from a graph
Annette [7]

Answer:

Y-intercept: (0,-0.7)

X-intercept: (-1.2,0)

Explanation:

The Y-intercept is the spot where the line crosses the Y axis (the vertical axis). This always occurs where X=0. For this problem the Y value at this point is -0.7. So, for the coordinates (X,Y) X is 0 and Y is -0.7 so it is (0,-0.7)

The X-intercept is the spot where the line crosses the X axis (the horizontal axis). This always occurs where Y=0. For this problem the X value at this point is -1.2. So, for the coordinates (X,Y) X is -1.2 and Y is 0 so it is (0,-0.7)

Which of the following graph represents the equation y-2=3(x-1)​
pshichka [43]

Answer with explanation:

To draw the graph of linear equation of the form

  y-a=m (x-b)

We will first write it in slope intercept form which is of the form

   \frac{x}{a}+\frac{y}{b}=1\\\\\rightarrow y-2=3 \times (x-1)\\\\\rightarrow y-2=3 x-3\\\\\rightarrow 3 x-y=3-2\\\\\rightarrow 3 x-y=1\\\\\rightarrow \frac{x}{\frac{1}{3}}+\frac{y}{-1}=1

It will cut x axis and y axis at , (\frac{1}{3},0) \text{and} (0,1) respectively.

As Euclid postulate States that, Unique equation of line can be Determined by two points,So join these two points.And Infinite number of points lie on a line.

A triangle has a side length of 5.4 and 7 x x=​
Burka [1]

Answer:

D. 8.8

Step-by-step explanation:

As the pythagorean theorem.

A² + B² = C²,

5.4 × 5.4 + 7 × 7 = C²,

29.16 + 49 = C²,

78.16 = C²,

8.8 ≈ C
