Slope form

Find the equation of a line given the point X(8, 1) and slope -2.8. Arrange your answer in the form y = ax + b, where a, b are the constants.



Correct answer:

a =  -2.8
b =  23.4

Step-by-step explanation:

(yy0)=a(xx0) (y1)=2.8(x8) y1=2.8x+22.4 y=2.8x+22.4+1 y=2.8x+23.4  a=2.8 b=23.4
