Graph the line with slope <br> 3/4<br><br><br> passing through the point (1,4)<br><br><br> .
Valentin [98]

To graph the line, we must first find out the equation for the line in slope-intercept form (y = mx + b). So far, we only have the slope, so the line's equation is y = 3/4x + b. But, by inserting the values of x and y in the point we know, we can find the y - intercept.


4 = 3/4 + b


b = 13/4


That means that the equation of our line is y = 3/4x + 13/4. Now we can graph. But, there is another way to go about (slightly faster too). Since we know the coordinates of 1 point, we can put that line down. Then, since we know that slope is rise over run, we can say, that with a slope of 3/4, one would go 3 points up for every 4 to the right. Now we can go 3 points up and 4 points to the right of point (1,4). That would be (5, 7). Now we can graph (since we have 2 points, or an equation).


The graph looks like this:

Please help will give BRAINLIEST if right
goldfiish [28.3K]

Answer:

h=4

Step-by-step explanation:

a^2 = h^2 + 4

b^2 = h^2 + 64

(2 + 8 )^2 = a^2 + b^2

100 = h^2 + 4 + h^2 + 64

100-68 = 2h^2

32 = h^2

h = 4
