Question

Find the x-intercept and the y-intercept for the graph of the equation. x - 3y = 3

a. 3; –2
b. 3; –1
c. 2; 0
d. 4; –1

Answer 1

x-intercept is the point where the graph cuts x axis
when a graph cuts x axis, y=0
when y=0, x-3(0)=3 i.e. x=3
so x intercept=3
y-intercept is the point where the graph cuts y axis
when a graph cuts y axis, x=0
when x=0, 0-3y=3 i.e. y=-1
so y intercept=-1
