What is the equation of the line that passes through (0, 3) and (7,0)? y-ix-3
3
y=x+3
3
y y=-7x+3
y=-x-3

The equation of the line in slope-intercept form is:

In one of the many possible standard forms:

Step-by-step explanation:

First calculate the slope of the segment that joins these two points: (0, 3) and (7,0):

Now, knowing that the y-intercept is (0, 3) [point on the y-axis (for x=0) where the line crosses], Then the equation of the line in slope-intercept form is:

And now, if you want to write the equation eliminating fractions, we can multiply both sides by "7":

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
