Slope intercept form is y = mx + b where M represents the slope and B represents the y-intercept.
2x = y + 7
Subtract 7 from both sides so that the y-variable is isolated by itself just like in the general form. Then simplify.
2x - 7 = y + 7 - 7
2x - 7 = y or y = 2x - 7
Wrong category though.
Driving and smoking are risks that are not currently well-understood.-----
false
Smoking:
Smoking is addictive, which means that once a person has smoked regularly for some time, his or her body will crave more smoking, especially when the body's level of nicotine begins to drop because nicotine is leaving the body and no new dose has been ingested to replace it. Smokers probably cannot stop themselves from having these desires, but they may still be able to refrain from acting on them.
Driving :
Driving while you are distracted (e.g., while you are texting or using your cell phone). Driving when you are fatigued. Driving too fast when the roads are slippery or when weather is bad, such as in fog, rain, snow. Ignoring traffic laws, such as speeding, passing a stop sign/light, passing illegally, etc.
