Answer:

Step-by-step explanation:

Y= -3x + 4..........(1)

Y= 4x - 10...........(2)

Substituting (1) into (2)

-3x + 4 = 4x - 10

-3x - 4x = -10 - 4

-7x = -14

x = -14/-7

x = 2

Putting x in (2)

y = 4(2) - 10

y = 8 - 10

y = -2

20. If a certain linear function f(x) is evaluated at 0, the answer is 4.
bija089 [108]

Answer:

y = (1/3)x + 4

Step-by-step explanation:

Two points on this line are (0, 4) and (3, 5).

As we move from the first point to the second, x increases by 3 and y increases by 1.  Thus, the slope, m, of the line is m = rise / run = 1/3.

Use the slope-intercept equation:  y = mx + b.

If we use the data from the point (0, 4), we get:

4 = (1/3)(0) + b, so that b = 4.  The desired equation is y = (1/3)x + 4.
