Question 316665: I need an example of how to do a group of problems. They are asking me to write the slope-intercept form of the eqation of the line through the given point with the given slope an example of a problem is
through:(-4,-3), slope= 5\4
once i see how to do one of them i will be able to do the rest please help me.

Use the other form of a line, the point-slope form and convert to slope-intercept.
y-yp=m%28x-xp%29
y-%28-3%29=%285%2F4%29%28x-%28-4%29%29
y%2B3=%285%2F4%29%28x%2B4%29
y%2B3=%285%2F4%29x%2B5
highlight%28y=+%285%2F4%29x%2B2%29+

slope-intercept: y=mx+b
through:(-4,-3), slope= 5\4
so we have :
x=-4
y=-3
m=(5/4)
find b
y=mx%2Bb
%28-3%29=%285%2F4%29%28-4%29%2Bb cross cancelled the 4's leaving 5 times -1
%28-3%29=%28-5%29%2Bbadd 5
2=b
rewrite equation
highlight%28y=%285%2F4%29x%2B2%29
