Resolved Question:

1. Graph the equation y=4. 2. Find the y-intercept and the x-intercept for the equation 3x+5y=45. 3. Solve using the miltiplication principle -6x>1/13. 4. Find the y-intercept and the x-intercept for 6x-5y=20. 5. Solve using the addition and multiplication principles 2.4x+19.2>48.0-7.2x. 6. Graph the line containing the given pair of points and find slope. (-3,4) (2,1)

2. 3x + 5x = 45 x-intercept is found when y = 0 if y = 0, 3x+ 5*0 = 45 or 3x = 45 when 3x = 45, x = 15. So x-intercept is (15, 0) y-intercept is found when x = 0 if x= 0, 3*0 + 5*y = 45 5y = 45 y = 9, So, y-intercept is (0,9)

3.

-6x > 1/13 divide both sides by -6 (-6/-6)x < (1/13)/-6 Note that the direction of the sign (>) becomes (<). Always do that when dividing or multiplying by a negative number

x < 1/13 * 1/-6 x< 1/-78 x< -1/78

4. 6x-5y=20

When x = 0 -5y = 20 y = -4 y-intercept is (0, -4)

When y = 0 6x = 20 x = 20/6 = 3.3333 x-intercept is (3.333, 0)

5. 2.4x+19.2>48.0-7.2x add 7.2x to both sides 2.4x+7.2x + 19.2 > 48.0 9.6x + 19.2 >48.0 subtract 19.2 from both sides

9.6x > 48.0 - 19.2 9.6x > 28.8 Divide both sides by 9.6 we get x > 3
