Let x=height. then base is x+4. plug what we know into the formula for the area of a triangle

A=½bh

16=½*(x+4)*(x)

32=x²+4x

x²+4x-32=0
(x+8)(x-4)=0
so x can be-8 our 4. when we plug-8 in for x we get a negative height. since a triangle cannot have a negative side length we discard-8 and try 4. height=4 and base=8

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)}   <em>point-slope form</em>

\boxed{y=-2x+3}     <em> slope-intercept form</em>

\boxed{2x+y=3}       <em>standard form</em>
