Answer:
x-intercept=(5,0) y-intercept =(0,-6)
Step-by-step explanation:
to find the x-intercept you substitute 0 in for y so the you're left with 6x=30 and you divide it by 6 on both sides leaving you with x=5
To find the y- intercept you set x=0 which leaves you with -5y=30 and you divide both sides by -5 and you're left with y=-6
Hope THIS works if not ask a tutors
