Find the y intercept for each of the following equations:

(a) 5x+y=9 The y intercept occurs where the line crosses the y axis, which is the point where x = 0. Setting x = 0 in (a) above and solving for y, we have 5(0)+y=9 y=9 Uniting the two pieces of information, the y intercept is (0.9). (b) 7x-4y=56 Setting x = 0, (c) y 5x 17 Setting x=0. 7(0)-4y=56 -4y=56 y=-14 y intercept: (0,-14) y=5(0)-17 y=-17 y intercept: (0,-17) If the equation is in the slope-intercept form y = mx + b as in (c), the y intercept (0, b) can be inferred directly from the equation, as was explained in Example 7. (d) y 18x33 y intercept: (0, -33) (e) y=3x+ (S) y=x-2 y intercept: (0,) y intercept: (0, -2)
