Question

The straight line l is parallel to  y + 5x = 1, and passes through the point P(2, 3). Find
its x-intercept

baldymcgee6 · Answer

Well, we know that the slope of the parallel line is the same as the slope of the line of the given function

anonymous · Answer

5x?

baldymcgee6 · Answer

we have y = -5x +1, right?

baldymcgee6 · Answer

the general form of a line is y = mx+b, where m is the slope

baldymcgee6 · Answer

do you get that?

anonymous · Answer

yes, so to find the x intercept do we have to plug it in to the form of a line?

baldymcgee6 · Answer

first we need to find the equation of the parallel line, so now that we know the slope is m =-5, and they gave us the points (2,3)...

y = mx+b
3 = -5(2) +b
b = 13

y = mx+b
y = -5x +13

x intercept is when y=0

0 = -5x +13
-13 = -5x
x = 13/5

x int. is at (13/5, 0)
