The general form of a line is y = mx + b. (m = slope, b = y-intercept)
So if we compare the line you've been given with the general form, you'll find that:
y = mx + b
y = 7x - 4
m = 7 and b = -4, therefore your slope is 7 and your y-intercept is -4. :)
y=mx+b
so m is the slope that is -7 in the equation y=−7x+4
To find y-intercept, let x = 0
y=−7(0)+4=4
(0, 4) is the y-intercept
Answer:-7, y-intercept (0, 4)
Hope this helps!
