If the model is good, then both points will check in the equation. Substituting 8 for x and 5 for y in the equation results in 56 – 50 = 3, which is not true. Therefore, the model is not good. Using (–12, –9) as a check results in –84 + 90 = 3. The constant value in the equation should be 6, not 3. In slope-intercept form, the y-intercept should be –3/5. Which facts did you include in your response? Check all that apply. The points do not make the equation true. The correct equation in standard form is 7x – 10y = 6. The y-intercept should be –3/5.
