Answer:
3
Step-by-step explanation:
-2 + 40x + 62 = 180 They are same side interior angles and add to 180
solve for x
40x + 60 = 180
40x = 120
x=3
Step 1: begin by writing the formula for slope intercept form
step2: substitute the given slope for X
step3: use the order pair you given (x,y) and substitute these values for the variables x and y in the equation
step4: solve for y ( y-intercept of the graph)
step5: rewrite the original equation in step 1 substituting the slope for x and the y-intercept for y
