X – y = 3 (line a)

tester [92]

Answer. You must first put the equation into slope-intercept form (y = mx + b). To do this, subtract x from both sides to isolate y. Then, since y will be negative, divide each side by -1, resulting in y = x - 3.

What is the value of z?

UNO [17]

Answer:

z =23

Step-by-step explanation:

The three angles in a triangle add to 180 degrees.

62+95+z = 180

Combine like terms

157 +z = 180

Subtract 157 from each side

157-157 +z = 180-157

z =23
