Slope of 3 mean y=3x
to find the equation we say y=3x+C then sub -2 for x and -8 for y to find the C
-8=3*-2+C
-8=-6+C
-8+6=C
-2=C
so equation would be: y= 3x-2

In slope intercept form, write the equation for the line that passes through the point (2,3) and the point (7,13).
tatuchka [14]
First, Use the slope equation to find the slope of the line passing thru these two points:

m=rise/run

Here, the rise is 13-3, or 10, and the run is 7-2, or 5.  Thus, the slope, m, is 10/5, or 2:  m=2.

We want the slope-intercept form, so let's begin with its general form:

y=mx+b.  Substitute the slope 2 for m:  y=2x+b.  Now choose either of the given points.  Arbitrarily I am choosing (2,3).  Then x=2 and y=3.

Substituting these values into y=2x+b:    3 = 2(2) + b, or b= 3 -4, or b = -1.

Then the equation of this line, in slope-intercept form, is y = 2x - 1.

Solve the equation.<br> a/4 − 5/6= −1/2
Masteriza [31]

Answer: a = 4/3

Step-by-step explanation:

1. a/4 − 5/6= −1/2 convert -1/2 to -3/6

2. a/4 = 5/6 - 3/6 = 2/6 = 1/3

3. a = 4*2/6 = 4*1/3

4. a = 4/3
