Write an equation in slope-intercept form for the line with slope

This would be easy for you if you know what the slope intercept form is.
y = mx + b this is the formula. M is where you put the slope and b is where the y-intercept goes. Now let's plug the numbers in. 
The slope you said is -23 so that goes into the place of m. X is the variable. I'll give you an example. Say Mary put $100 into her bank account and every week she took 23 dollars. x would the number of weeks because it can change. 
So back to plugging the numbers in. This is what it will look like when we put -23 in. 
y = -23x + b. As we said above, b is the y-intercept. This is the point where the line on the graph crosses the vertical line, which is y. x is the horizontal line.
You said the y-intercept is -4 so the line crosses the vertical line at the point -4. 
Plug this number into our formula, 
y = -23x + -4. 
There you go! We are finished making our slope intercept form equation.
I hope you understood, and good luck to you in the future.

An arc is 6.5 cm long and it subtends a central angle of 45 degrees. Find the radius of the circle.
Orlov [11]
Arc length = radius * central angle (measured in radians)
There are <span> <span> <span> 57.2957795131 </span> </span> </span> degrees per radian so
45 degrees = (45 / <span> <span> <span> 57.2957795131) = </span></span></span> <span> <span> <span> 0.7853981634 </span> </span> </span> radians<span><span> </span> </span>
radius = arc length / central angle (radians)
radius = 6.5 / <span> <span> 0.7853981634 </span> </span> radians = <span> <span> <span> 8.2760570408 </span> </span> </span> cm

2d +9= 19<br> The solution is d =
Novosadov [1.4K]

{\huge{\boxed{\mathbb{QUESTION}}}

2d +9= 19

The solution is d =

{\huge{\boxed{\mathbb{ANSWER\:WITH\:EXPLANATION}}}

Hello there, first we can place our equation, which you have stated

2d+9=19, this algebra, in algebra we want to find the exact value of the variable, or have the variable on one side of the equation.

First we can subtract 9 with both sides of the equation giving us the result of 2d=10, this can also be represented as 2\cdot d=10, now just divide both sides of the equation by 2, our answer is d=5.
