Question 251377
<font face="Garamond" size="+2">


The *[tex \Large x]-intercept is a point with coordinates *[tex \Large \left(a,0\right)] which is the value that *[tex \Large x] assumes when *[tex \Large y\ =\ 0]


So, to find the *[tex \Large x]-coordinate of the *[tex \Large x]-intercept, set *[tex \Large y] to zero and solve the resulting single-variable equation for *[tex \Large x].


So you would solve:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0\ =\ -\frac{3}{4}x\ +\ 3]


for *[tex \Large x] and then replace *[tex \Large a] in *[tex \Large \left(a,0\right)] with that value giving you your *[tex \Large x]-intercept.


Finding the *[tex \Large y]-intercept is the same process, except that the coordinates of the *[tex \Large y]-intercept are *[tex \Large \left(0,b\right)] and so, to find the *[tex \Large y]-coordinate of the *[tex \Large y]-intercept, set *[tex \Large x] to zero and solve the resulting single-variable equation for *[tex \Large y].


So you would solve:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y\ =\ -\frac{3}{4}(0)\ +\ 3]


for *[tex \Large y] and then replace *[tex \Large b] in *[tex \Large \left(0,b\right)] with that value giving you your *[tex \Large y]-intercept.
