Will mark brainliest fast ! what is an equation in point-slope form for the linear function whose graph contains the points (4,-7) and (5.o)? show your work.

y - (-7) = 7(x - 4)

Step-by-step explanation:

The given points are (4. -7) and (5, 0).

The point-slope equation of a line is

y - y1 = m(x - x1),

where (x1, y1) is a point on the line, and m is the slope.

m = (y2 - y1)/(x2 - x1) = (-7 - 0)/(4 - 5) = -7/(-1) = 7

You can use either point for (x1, y1). I will use point (4, -7).

y - (-7) = 7(x - 4)

-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
