Mathematics
1 answer:

Answer:

y = 2x - 2

Step-by-step explanation:

y= mx+b

m= slope

b= y-intercept (point on line where x= 0.... or the point where the line hits the y-axis)

Determine slope by using slope formula or by counting boxes

By counting boxes, you can see that each point is 2 units up, 1 unit right (2/1)

the slope is 2

the point where the line is touching the y-axis is (0, -2)

m = slope = 2

b  = y-intercept = -2

y = 2x + (-2) OR y = 2x -2

I need help plsssssssssssssssssssssss
Slav-nsk [51]

Answer:

7x + 34 = 90

-34          -34

7x = 56

Divide by 7 on both sides:

X = 8 degrees

A right angle equals 90 degrees so that must mean angle 7x + 34 must equal to 90 so we solve for x.

A triangle equals = 180 degrees

A quadrilateral equals = 360 degrees

A right angle equals = 90 degrees

A straight line equals = 180 degrees
