Writing and Evaluating an Expression Write and evaluate the expression. Then, select the correct answer. The sum of forty-five and a number, evaluate when n = 1.1 O 45n, when n = 1.1, the value is 49.5 O 45 + n, when n = 1.1, the value is 46.1 O 45 – n; when n = 1.1, the value is 43.9. o when n = 1.1. the value is 0.024.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
