4)
3x-2y=10
5x+y=4

We solve this system of equation by elimination method.
   3x-2y=10
2(5x+y=4)
------------------------
13x=18

Answer: A)  13x=18

5)
slope-intercept form:
y=mx+b
y=f(x)

m=slope
b=y-intercept

1) we calculate the slope:
we choose any two points of this table:
For example: (2,2) and (3,4)

Given two points (x₁,y₁) and (x₂,y₂) the slope of the line that passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)
In this case:
m=(4-2)/(3-2)=2

2) we compute "b";
we choose an any point of this talbe:
For example: (4,6), and we substitute "x" for "4" and "y" for "6" in the next equation:
y=2x+b  
6=2(4)+b
b=6-8
b=-2

3) we build the function that it belong this table:
m=2
b=-2
f(x)=mx+b
f(x)=2x-2

Answer: B) f(x)=2x-2

Find an equation for a line parallel to 4x + 5y + 2 = 0, with an x-intercept of 3
katen-ka-za [31]

\bf 4x+5y+2=0\implies 5y=-4x-2\implies y=\cfrac{-4x-2}{5} \\\\\\ y=-\cfrac{4}{5}x-\cfrac{2}{5}\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}


so, notice, the slope of that equation is just -4/5, and any parallel line to it will have the same exact slope.

so we're really looking for the equation of a line whose slope is -4/5 and runs through x-intercept of 3, namely (3,0).


\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{0})~\hspace{10em} slope = m\implies -\cfrac{4}{5} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-0=-\cfrac{4}{5}(x-3)\implies y=-\cfrac{4}{5}x+\cfrac{12}{5}
