Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
The answer is letter 4 you can prove this replacing each pair in the function y=3x+5, and it is a straight line because the greatest exponent of this function is 1.
Answer:
В (50°)
Step-by-step explanation:
m∠XWY=180-95=85°
x=180-(m∠XWY+m∠XYW)=180-(85+45)=50°
