Write the slope-intercept form of the equation of the line through the given point with the given slope.

Answer: $\textsf{y = x + 2}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{Slope = 1, Goes through (-1, 1)}$

Find: $\textsf{Determine the slope-intercept form of the equation}$

Solution: In order to determine the equation we need to first use the point-slope form which uses a slope and a point which can then be simplified and solve for y to get the slope-intercept form.

<u>Plug in the values</u>

$\textsf{y - y}_2\textsf{ = m(x - x}_1\textsf{)}$

$\textsf{y - 1 = 1(x - (-1))}$

<u>Simplify and solve for y</u>

$\textsf{y - 1 = 1(x + 1)}$

$\textsf{y - 1 + 1 = x + 1 + 1}$

$\textsf{y = x + 2}$

Therefore, the simplified equation in slope-intercept form would be y = x + 2

The rainfall total two years ago was 10.2 inches. Last year's total was 20% greater. What was last year's rainfall total?

andre [41]

20% greater = 1.2 times

so 10.2 x 1.2 is the answer. it is C.

Answer:

P + Q = 1

Step-by-step explanation:

Given: $\frac{1+\sqrt{3} }{1-\sqrt{3} }$ = P - $\sqrt{Q}$

This is a question on surd, so we need to rationalize the denominator to have;

$\frac{1+\sqrt{3} }{1-\sqrt{3} }$ * $\frac{1+\sqrt{3} }{1+\sqrt{3} }$ = $\frac{1+\sqrt{3}+\sqrt{3} + 3}{1+\sqrt{3}-\sqrt{3} -3 }$

= $\frac{4+ 2\sqrt{3} }{1-3}$

= $\frac{4+2\sqrt{3} }{-2}$

= -2 - $\sqrt{3}$

Thus,

-2 - $\sqrt{3}$ = P - $\sqrt{Q}$

⇒ P = -2 and Q = 3

Therefore, the value of P + Q = -2 + 3

= 1

Thus,

P + Q = 1
