Answer:
Let's put this function into slope-intercept form.
y = mx + b
where m is the slope
and b is the y-intercept
We know the y intercept is -3 since f(0) = -3
Thus, b = -3
To find the slope, use the equation m = (y1 - y2) / (x1 - x2)
x1 = 0
y1 = -3
x2 = 7
y2 = 11
Note: these values came from the given information
m = (-3 - 11) / (0 - 7)
= (-14) / (-7)
= 2
m = 2
Plug the values of m and b into y=mx + b
y = 2x - 3
That's your answer.
