b=4, m=3

Explanation:

The intercept and slope are already given. This equation is in the form y=mx+b, where b is the y-intercept (0,4) and m is the slope, 3.

Slope: 3
Y-Intercept: (4,0)
X-Intercept: (0,-4/3)

Explanation:

You should be armed with the knowledge what the slope-intercept form is. It is y=mx+b. m stands for the slope, and b stands for the y-intercept. So, seeing from the equation, y=3x+4, 3 is the slope and (4,0) is the y-intercept. To find the x-intercept, you have to plug 0 in for y and just solve for x. Then, you should have 0=3x+4. You subtract 4 to isolate the variable. Lastly, you divide 3 to get -4/3. The x-intercept is (0,-4/3)
