Question 154494: Hi, I have a problem with figuring out a linear equation. The question asks me to plot the graph showing the point and slope specified in the equation. Then I must rewrite in slope-intercept form and standard form.
Here is the equation
y-3=2/5(x-2)
Please help me.
Thanks

You can put this solution on YOUR website! Hi, I have a problem with figuring out a linear equation. The question asks me to plot the graph showing the point and slope specified in the equation. Then I must rewrite in slope-intercept form and standard form.
Here is the equation
You must learn the three forms of the equation of a line:
1. Point-slope form:
where the point (,) is on the line,
and represents the slope of the line.
----------------------------
2. Slope-intercept form:
where is the slope of the line and (0,)
are the coordinates of the y-intercept.
-----------------------------
3. Standard form:
Where A, B, and C are whole numbers, and A is positive.
[Don't confuse the capital B with the small b in the slope-
intercept form.
-----------------------------
Multiply both sides by 5 to clear of
fractions:
··
Multiply through by -1 to make the first
coefficient positive:
That is the standard form.
----------------------------
To get the slope-intercept form, solve
that for y:
