What do you need help with?
To find the slope you need to take the rise/run, which means the change of y divided by the change of x. So -7.3-2.7 is the change of y and 1.3-(-4.7) is the change in x. So the slope is equal to -1.666. Then if you take the x and y for one set of points and put them into y = -1.666x + b and solve for b to give you the intercept. So -7.3 = (-1.666)(1.3) + b, therefore b = -5.1342. Now the equation is y = -1.666x + -5.1342
Can I see the problem? Maybe I can help you. You just need to specify.
Answer:
f(-2) = -7
Step-by-step explanation:
f(-2) = 2(-2) - 3
