We know that in order to solve a math problem, we need an equation. Luckily there's an equation to find the slope and intercept of a (straight) line!
Because of the equation:
Y = mx + b
You can use it to find the Y intercept, and then therefore slope (or the other way around)!
First, look at the point where the line meets with the y axis.
It's not clear, but it's 7.
That's your 'Y intercept'. Easy!
Then, to find the slope. There are a couple of ways to find it, but I'll show you the one using the y = mx + b equation.
In the equation, 'b' represents the Y intercept. Since we already know our Y intercept on the graph is 7, we can plug that into the equation.
Y = mx + 7
What's m? M is the slope of the line. In order to find this, we need more numbers to work with. Numbers from the line's coordinate points.
Since coordinates in a graph have x and y, we can plug in any coordinate from the graph's line into our equation (y = mx +7).
I choose...this point (points at random coordinate on line).
(3, 10) aka (x, y)
It's on the line, right? So it will be a reliable x and y.
Put the numbers in...
10 = 3m + 7
This looks a bit easier, right? Now we solve for m (the slope)!
Combine like terms.
10 - 7 = 3m
Divide the 3.
3/3 = m
m = 1.
That's your slope!
So, taking the solution, we can determine that the slope of the line is 1, and the intercept of the line is 7.
Y = x + 7
Hope it helps! This is the most I can do for you :)

Answer:
a +b = 2
Step-by-step explanation:
a +3 = 6
a = 6 -3
a = 3
Plugin a =3 in the equation,
a*b +5*a +3*b + 15 = 24
3b + 5*3 + 3b + 15 = 24
3b + 15 + 3b + 15 = 24 {combine like terms}
3b + 3b + 15 + 15 = 24
6b + 30 = 24 {Subtract 30 from both sides}
6b = 24 -30
6b = -6 {divide both sides by 6}
b = -6/6
b = -1
a + b = 3 + ( -1)
= 2
