Answer

a) The x-intercept is $12$ The y-intercept is $-10$ b) The x-intercept is $4$ The y-intercept is $\frac{3}{2}$

Work Step by Step

a) $5x-6y=60$ To find the x-intercept, substitute $0$ for $y$. Solve for $x$. $5x-6(0)=60$ $5x=60$ $x=12$ To find the y-intercept, substitute $0$ for $x$. Solve for $y$. $5(0)-6y=60$ $-6y=60$ $y=-10$ b) $3x+8y=12$ To find the x-intercept, substitute $0$ for $y$. Solve for $x$. $3x+8(0)=12$ $3x=12$ $x=4$ To find the y-intercept, substitute $0$ for $x$. Solve for $y$. $3(0)+8y=12$ $8y=12$ $y=\frac{3}{2}$
