Answer:
y = 5x + 4
Step-by-step explanation:
The slope always goes before the x and your y-intercept is plus or minus depending on weather it is positive or negative. Your parent function or standard equations) is y = mx + b, so just plug your variable into there.
Using complementary angles, <X is equal to <Z, so it's <Z = 35°.
The answer is 70/100ths i am pretty sure
