Write a equation of the lines passes through the given points (-2,7) (1,1) the equation is?

vredina [299]

The point-slope form:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-2, 7) and (1, 1). Substitute:

$m=\dfrac{1-7}{1-(-2)}=\dfrac{-6}{3}=-2$

$y-7=-2(x-(-2))\\\\\boxed{y-7=-2(x+2)}$ point-slope form

$\boxed{y=-2x+3}$ slope-intercept form

$\boxed{2x+y=3}$ standard form

Write y=10x as a logarithmic function please

Margaret [11]

$\bf \textit{exponential form of a logarithm}
\\\\
log_a b=y \implies a^y= b\qquad\qquad 
% exponential notation 2nd form
a^y= b\implies log_a b=y \\\\
-------------------------------\\\\
y=10^x\implies log_{10}(y)=x$

The graph of h (x) = StartAbsoluteValue x minus 10 EndAbsoluteValue + 6 is shown. On which interval is this graph increasing

k0ka [10]

Answer:

x≥10 or x∈[10, ∞)

Step-by-step explanation:

The graph we are given is h(x) = |x-10|+6, which has the shape of a V. The vertex is at (10, 6), so to the right of the vertex, the graph is increasing.

Therefore, the graph increases during the interval x≥10 or x∈[10, ∞).
