Please help quickly I will be so thankful to anyone that helps

Answer 1

Answer:

f(x)=3+1.25 or f(x)=3+1 1/4

Step-by-step explanation:

To get the slope of then line when it is not given to you,you use the formula Y2-Y1 /X2-X1 and u pick to point on the line that are secured or more known as counted points and u get the coordinates of the point and u plug them into the  equation and u get the slope which is 3 then u get b which is the y-intercept which i can tell is 1.25

Answer 2

points (2,2) and (0,-4)

first find slope -4 -2/0-2 = -6 /-2 = 3

now plug in slope and one of the points into formula y-y1 = m(x-x1)

(y-2) = 3 (x -2)

y-2 = 3x -6

y = 3x -6+ 2

y = 3x -4
