Question

4x + 3y = 5 2x – y=5 Use substitution method

Answer 1

Answer:  Slope = -2.667/2.000 = -1.333

 x-intercept = 5/4 = 1.25000

 y-intercept = 5/3 = 1.66667

Step-by-step explanation: Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.667 and for x=2.000, the value of y is -1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -1.000 - 1.667 = -2.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
