Answer:

x = ± $\sqrt{\frac{c-b}{a} }$

Step-by-step explanation:

Given

ax² + b = c ( subtract b from both sides )

ax² = c - b ( divide both sides by a )

x² = $\frac{c-b}{a}$ ( take the square root of both sides )

x = ± $\sqrt{\frac{c-b}{a} }$

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.
