Answer :
y = 4x - 19...slope here is 4...parallel lines will have the same slope
y = mx + b
slope(m) = 4
(0,7)...x = 0 and y = 7
now sub
7 = 4(0) + b
7 = b
so ur equation is : y = 4x + 7
y = mx + b
slope(m) = 4
(0,7)...x = 0 and y = 7
now sub
7 = 4(0) + b
7 = b
so ur equation is : y = 4x + 7
If you are looking for an equation that is parallel to y = 4x -19, we know the answer must have the same slope. The slope of the given equation is 4 (because m = 4 in this case), therefore, we can eliminate answers a) and b). Next, we need a y-intercept, or "b". I will take the equation of a line:
y = mx + b, substutute the given (0, 7) into the equation 7=m(0) + b, and substitute the 4 as the slope, so 7 = 4(0) + b. Simpllify this to 7 = b. Find an answer that has 7 as the "b" and 4 as the "m", and we have answer D.
