Answer: y = 7x - 3

graphed equation attached

Step-by-step explanation: Slope-intercept form . y= mx+b

m is the slope, b is the constant, the y-intercept.

First find the slope: rise/run

Rise is the difference in y-values 18-4 = 14

Run is the difference between x-values 3 - 1 = 2

The Slope is 14/2 simplify:

m = 7

Use this calculated slope with values of y and x from either of the given coordinates and calculate b

y = mx + b

18 = 7(3) + b

18 = 21 + b . subtract 21 from both sides 18 - 21 = 21 -21 + b

-3 = b

Put these calculated values for m and b into the slope-intercept equation"

y = 7x - b

Enter the equation of the line in slope-intercept form. The line passes through (1.4) and-example-1
