Q. 5.) Find the intercepts of each equation and graph3x−5y=30
Find y-intercept: Find the y-intercept by setting x to 0. To find the y-intercept, we substitute x=0 into the equation and solve for y. 3(0)−5y=30−5y=30y=−6 The y-intercept is the point (0,−6).
Find x-intercept: Find the x-intercept by setting y to 0. To find the x-intercept, we substitute y=0 into the equation and solve for x. 3x−5(0)=303x=30x=10 The x-intercept is the point (10,0).
Graph the intercepts: Graph the intercepts and draw the line. Plot the y-intercept (0,−6) and the x-intercept (10,0) on a coordinate plane. Draw a line through these two points to represent the equation 3x−5y=30. This line will extend infinitely in both directions and will cross the y-axis at (0,−6) and the x-axis at (10,0).
