On the graph of the equation 2x + 5y = 30, what is the value of the yintercept
can you please help? i dont understand
also To which graph does the point (8, 2) belong?
and What is the slope of the line that passes through (1, 4) and (1, 3)?

The yintercept, as the name suggests, is the point where a line crosses the yaxis. The xvalue of a yintercept is always zero (because that’s where the yaxis is).
When a linear equation is in the form y = mx + b, the yvalue of the yintercept is b. So, if you manipulate the given equation into that form, you’ll find the yintercept.
2x + 5y = 30
5y = 2x – 30
y = (2/5)x – (30/5)
y = (2/5)x – 6
The yvalue of the yinterecept is thus 6. So, the coordinate of the yintercept is (0,6)

Yintercept means that X=0
So 2(0)+5y=30
5y=30
Yintercept=6
I did not understand the second question about which graph… But the slope you should know the formula y2y1/x2x1 x1=1 y1=4 x2=1 y2=3
So 34/11 7/0 so the slope is a straight vertical line (from up to down)

the yintercept is the value on the graph where x = 0
2(0) + 5y = 30
5y = 30
y = 30/5 = 6
that’s it– the yintercept is 6 (or the point (0 , 6))

It is 6. One simple way is taking x as zero and solving the equeation. Or draw the graph and point at which the line intersects th eyaxis is the y intercept.

It’s 6
