Equation is y = 2x + 2
Step-by-step explanation:
Find slope of the line using the formula m = (y2 - y1)/(x2 - x1)
Here, x1 = -2, x2 = 4, y1 = -2, y2 = 10
⇒ m = (10 - -2)/(4 - -2) = 12/6 = 2
Slope-intercept form equation is y = mx + b
⇒ y = 2x + b
Find the y-intercept, b. Since the line passes through (4, 10) substitute values of x = 4 and y = 10 to find b.
⇒ 10 = 2 × 4 + b = 8 + b
⇒ b = 2
Form the equation
⇒ y = 2x + 2
250 seconds : x minutes
250 sec : x min * 60 seconds (because there are 60 seconds in 1 minute)
250/60 sec : x min
x = 4.167 min
hope this helps
(r+b-g)(b-g)
I this question , we have the values of r,b and g given , which are r=9,b=5,g=6
And we have to find the value of the given expression . And for that we need to substitute the values of r,b and 9 in the expression. That is ,
(9+5-6)(5-6) = 8(-1) = -8
So the value of the given expression is -8.
From my research on the internet, the image attached supports this problem. The two lines are parallel, as supported by the converse of corresponding angles postulate. It states that:<span> If a </span>transversal<span> intersects two lines and the corresponding angles are </span>congruent<span>, then the lines are parallel.</span>
