Answer:

one solution : (2,2)

Step-by-step explanation:

hello :

the system is : x-2.6y=-3.2 ....(*)

                         -x+4.5y=7.....(**)

add(*) and(**) : -2.6y+4.5y = -3.2+7

                         1.9y=3.8

y = 3.8/1.9 =2

put this value in (*) : x - (2.6)(2) =-3.2

x =(2.6)(2) -3.2 =2

Write the equation in slope-intercept form of the line that has a slope of -7/8 and contains the point (-4, 9).
lubasha [3.4K]

Answer:

The equation of the line is y = -7/8x + 11/2

Step-by-step explanation:

Since we have the slope and a point to start, we can use point-slope form to find the equation.

y - y1 = m(x - x1)

Use the slope for m and the point at (x1, y1). Then solve for y.

y - 9 = -7/8(x + 4)

y - 9 = -7/8x - 7/2

y = -7/8x + 11/2
