The equation is y=5x-30.The y-intercept is (0,-30) and the x-intercept is (6,0)

Work Step by Step

A)Make the equation.y=mx+b where the m value is 5 because that's the charge of each pet and the b value is -30 because you spent 30 dollars on supplies which is a loss so it is negative. B)Let x=0 to find the y-intercept: y=5x-30 y=5(0)-30 y=-30 Let y=0 to find the x-intercept: y=5x-30 0=5x-30 30=5x 6=x So it is (0,-30) and (6,0)
