Which is the equation in slope-intercept form of the line that contains points A and C?
Delvig [45]
We have that
point C(-2,-4)
point A(-4,-2)

we know that
the equation of a line in the intercept form is
y=mx+b

Step 1
find slope m
m=(y2-y1)/(x2-x1)
m=(-2+4)/(-4+2)------> 2/-2-------> m=-1

Step 2
find the value of b
with m=-1 and point C(-2,-4)
-4=-1*(-2)+b--------> -4=2+b-------> b=-6
y=mx+b
y=-x-6

the answer is
y=-x-6

The equation for a line is 4x -3y=24. What is the slope of the line?
eimsori [14]

\bf 4x-3y=24\implies 4x-24=3y\implies \cfrac{4x-24}{3}=y \\\\\\ \cfrac{4x}{3}-\cfrac{24}{3}=y\implies \stackrel{\stackrel{m}{\downarrow }}{\cfrac{4}{3}}x-8=y~\hspace{5em} \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}
